Their error is two-fold. First, whether or not Israel even existed has nothing to do with what Islam's "sacred" texts state. Second, YHWH's command to displace and slaughter inhabitants of Canaan is in no way morally equivalent to Allah's commands to rape, enslave, and slaughter all who refuse the "invitation" to Islam and the demand for jizya and submission.
So, what was the command to Israel? It was not genocide YHWH intended:
"I will send my terror before you and will throw into confusion all the people against whom you shall come, and I will make all your enemies turn their backs to you. And I will send hornets before you, which shall drive out the Hivites, the Canaanites, and the Hittites from before you. I will not drive them out from before you in one year, lest the land become desolate and the wild beasts multiply against you.Here is another proof that YHWH did not want everyone dead:
"Little by little I will drive them out from before you, until you have increased and possess the land. And I will set your border from the Red Sea to the Sea of the Philistines, and from the wilderness to the Euphrates, for I will give the inhabitants of the land into your hand, and you shall drive them out before you.
"You shall make no covenant with them and their gods. They shall not dwell in your land, lest they make you sin against me; for if you serve their gods, it will surely be a snare to you" (Exodus 23:27-33).
"the angel of the LORD . . . said, 'I brought you up from Egypt and brought you into the land that I swore to give to your fathers. I said, 'I will never break my covenant with you, and you shall make no covenant with the inhabitants of this land; you shall break down their altars.' But you have not obeyed my voice. What is this you have done? So now I say, I will not drive them out before you, but they shall become thorns in your sides, and their gods shall be a snare to you'" (Judges 2:1-3).What was the purpose? To kill innocent men, women, and children?
No, its purpose was to punish evil -- such as child sacrifice and the type of rampant, violent, sexual perversion for which Sodom and Gomorrah had been destroyed earlier -- and to set apart Israel as holy. This also prepared the way for the Messiah:
"And the LORD spoke to Moses, saying, "Speak to the people of Israel and say to them, I am the LORD your God. You shall not do as they do in the land of Egypt, where you lived, and you shall not do as they do in the land of Canaan, to which I am bringing you . . . .Here's one more:
"None of you shall approach any one of his close relatives to uncover nakedness . . . You shall not uncover the nakedness of . . . your mother . . . You shall not uncover the nakedness of your father's wife . . . You shall not uncover the nakedness of your sister, your father's daughter or your mother's daughter, whether brought up in the family or in another home. You shall not uncover the nakedness of your son's daughter or of your daughter's daughter . . . You shall not uncover the nakedness of your father's wife's daughter . . . since she is your sister. You shall not uncover the nakedness of your father's sister; she is your father's relative. You shall not uncover the nakedness of your mother's sister . . . You shall not uncover the nakedness of your . . . aunt. You shall not uncover the nakedness of your daughter-in-law; she is your son's wife . . . You shall not uncover the nakedness of your brother's wife . . . You shall not uncover the nakedness of a woman and of her daughter, and you shall not take her son's daughter or her daughter's daughter to uncover her nakedness; they are relatives; it is depravity. And you shall not take a woman as a rival wife to her sister, uncovering her nakedness while her sister is still alive.
"You shall not approach a woman to uncover her nakedness while she is in her menstrual uncleanness. And you shall not lie sexually with your neighbor's wife and so make yourself unclean with her. You shall not give any of your children to offer them to Molech, and so profane the name of your God: I am the LORD. You shall not lie with a male as with a woman; it is an abomination. And you shall not lie with any animal and so make yourself unclean with it, neither shall any woman give herself to an animal to lie with it: it is perversion.
"Do not make yourselves unclean by any of these things, for by all these the nations I am driving out before you have become unclean, and the land became unclean, so that I punished its iniquity, and the land vomited out its inhabitants. But you shall keep my statutes and my rules and do none of these abominations, either the native or the stranger who sojourns among you (for the people of the land, who were before you, did all of these abominations, so that the land became unclean), lest the land vomit you out when you make it unclean, as it vomited out the nation that was before you. For everyone who does any of these abominations, the persons who do them shall be cut off from among their people. So keep my charge never to practice any of these abominable customs that were practiced before you, and never to make yourselves unclean by them: I am the LORD your God" (Leviticus 18:1-30).
"When you come into the land that the LORD your God is giving you, you shall not learn to follow the abominable practices of those nations. There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the LORD. And because of these abominations the LORD your God is driving them out before you. You shall be blameless before the LORD your God, for these nations, which you are about to dispossess, listen to fortune-tellers and to diviners. But as for you, the LORD your God has not allowed you to do this. "The LORD your God will raise up for you a prophet like me from among you, from your brothers--it is to him you shall listen-- " (Deuteronomy 18:9-15).More to come, including Israel's approach into Canaan from the east across the Jordan, other commands, and Israel's facing the same fate at the hands of the Babylonians.
Comparing the Canaan texts in Scripture to Islamic Jihad texts is apples vs. oranges.Here is the Genesis 15 passage relating YHWH's promise to Abraham regarding his descendants: Slavery in Egypt; the Plagues, Passover, and Exodus; and the conquest of Canaan when the sin of the Amorites would reach "full measure."
Historically, God has used one nation to execute judgment on another. The Israelites to Canaan, The Assyrians and Babylonians to Israel, Persia to Babylon, etc.
This is a function of God's holiness. For example, He told Abraham in Genesis 15:16 that the sin of the Amorites had not yet reached a point where God was going to judge them, but it would come later. God cannot be mocked.
Ultimately, I think the jihadists are attempting to employ the same principle. The "infidels" have turned their backs on "god" and must be judged by the jihadist who is representing the "true faith".
Besides the enormous problem that they have a made-up "god" and a deeply flawed "holy text", there is also the problem of the moral chasm between YHWH judging child sacrificers and demon worshippers vs. jihadists forcing people to convert or die.
"As the sun was setting, Abram fell into a deep sleep, and a thick and dreadful darkness came over him. Then the LORD said to him, "Know for certain that your descendants will be strangers in a country not their own, and they will be enslaved and mistreated four hundred years. But I will punish the nation they serve as slaves, and afterward they will come out with great possessions. You, however, will go to your fathers in peace and be buried at a good old age. In the fourth generation your descendants will come back here, for the sin of the Amorites has not yet reached its full measure."Deuteronomy 7 sums up the topic well:
"When the sun had set and darkness had fallen, a smoking firepot with a blazing torch appeared and passed between the pieces. On that day the LORD made a covenant with Abram and said, "To your descendants I give this land, from the river [d] of Egypt to the great river, the Euphrates- the land of the Kenites, Kenizzites, Kadmonites, Hittites, Perizzites, Rephaites, Amorites, Canaanites, Girgashites and Jebusites" (Genesis 15:12-20).
"When the LORD your God brings you into the land that you are entering to take possession of it, and clears away many nations before you, the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations more numerous and mightier than yourselves, and when the LORD your God gives them over to you, and you defeat them, then you must devote them to complete destruction. You shall make no covenant with them and show no mercy to them. You shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, for they would turn away your sons from following me, to serve other gods. Then the anger of the LORD would be kindled against you, and he would destroy you [Israel] quickly. But thus shall you deal with them: you shall break down their altars and dash in pieces their pillars and chop down their Asherim and burn their carved images with fire.
"For you are a people holy to the LORD your God. The LORD your God has chosen you to be a people for his treasured possession, out of all the peoples who are on the face of the earth. It was not because you were more in number than any other people that the LORD set his love on you and chose you, for you were the fewest of all peoples, but it is because the LORD loves you and is keeping the oath that he swore to your fathers, that the LORD has brought you out with a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt. Know therefore that the LORD your God is God, the faithful God who keeps covenant and steadfast love with those who love him and keep his commandments, to a thousand generations, and repays to their face those who hate him, by destroying them. He will not be slack with one who hates him. He will repay him to his face. You shall therefore be careful to do the commandment and the statutes and the rules that I command you today.
"And because you listen to these rules and keep and do them, the LORD your God will keep with you the covenant and the steadfast love that he swore to your fathers. He will love you, bless you, and multiply you. He will also bless the fruit of your womb and the fruit of your ground, your grain and your wine and your oil, the increase of your herds and the young of your flock, in the land that he swore to your fathers to give you. You shall be blessed above all peoples. There shall not be male or female barren among you or among your livestock. And the LORD will take away from you all sickness, and none of the evil diseases of Egypt, which you knew, will he inflict on you, but he will lay them on all who hate you. And you shall consume all the peoples that the LORD your God will give over to you. Your eye shall not pity them, neither shall you serve their gods, for that would be a snare to you.
"If you say in your heart, 'These nations are greater than I. How can I dispossess them?' you shall not be afraid of them but you shall remember what the LORD your God did to Pharaoh and to all Egypt, the great trials that your eyes saw, the signs, the wonders, the mighty hand, and the outstretched arm, by which the LORD your God brought you out. So will the LORD your God do to all the peoples of whom you are afraid. Moreover, the LORD your God will send hornets among them, until those who are left and hide themselves from you are destroyed. You shall not be in dread of them, for the LORD your God is in your midst, a great and awesome God. The LORD your God will clear away these nations before you little by little. You may not make an end of them at once, lest the wild beasts grow too numerous for you. But the LORD your God will give them over to you and throw them into great confusion, until they are destroyed. And he will give their kings into your hand, and you shall make their name perish from under heaven. No one shall be able to stand against you until you have destroyed them. The carved images of their gods you shall burn with fire. You shall not covet the silver or the gold that is on them or take it for yourselves, lest you be ensnared by it, for it is an abomination to the LORD your God. And you shall not bring an abominable thing into your house and become devoted to destruction like it. You shall utterly detest and abhor it, for it is devoted to destruction." (Deuteronomy 7).
