The Torah: A Modern Commentary - W. Gunther PlautAn early attempt was made in Talmudic days. The Hebrew for "show them no pity" (lo teHannem) was read as "do not grant them [land]," as if the text read lo taHnem), that is, do not sell real estate to "them-a rendering which leaned on the warning in Exod. 23:33 not to let them dwell "in your land". But even if one would deem this interpretation feasible (which. it is not, in view of the clear Masoretic text), one could not argue away the provision of Deut. 20:16 which, using another word, unequivocally says, "You shall not let a soul remain alive.
The text has further been defended on the grounds of necessity: unless the native people were done away with, they would ensnare Israel with their idolatrous practices, and the maintenance of the Sinaitic covenant was a task overshadowing all else. God's plans for humanity could not and cannot be measured by human considerations. To emphasize this point, S. R. Hirsch interpreted the twice issued injunction of verses 2 and 16 to show that repetition was needed because it went so much against the sensibilities of the Israelites. However, no student of history can easily accept such a reading, for all too many humans have fallen victim to inquisitors and crusading warriors who pretended to act out of the highest religious motives. And already in talmudic times the notion was rejected that an Almighty God would agree to wipe idolatry off the face of the earth, though He had the power to do so.
One comes closer to an understanding of the Torah if one abandons efforts to shield it from criticism and sees it in the light of its own time, its values, and standards. "The custom to 'dedicate' an enemy to the deity, or to ban him, or after a victory to annihilate him, is told us of various Near Eastern nations as well as of the Greeks, Romans, Celts, and Germans. Since the sensitivities of the ancients were not offended by the rigor of this procedure, Moses could use this harsh war practice as a means to shield Israel from pagan infection .
But even this interpretation does not do the text full justice, for it ascribes to Moses a point of view which may not have been his at all. Moreover, and most important: the unyielding tenor of these provisions stands in sharp contrast to the fact that such a policy of annihilation was, never carried out-the Canaanites were not annihilated. In fact, in Judg. 3:1, God himself is said to have abrogated His original command (see above, at verse 22). Later, in retrospect-taking Deuteronomy to be a post-settlement and not a Mosaic document-the reader was told that the rampant idolatry which characterized Israel's history for centuries could have been avoided had the native peoples been destroyed. Note that the sermon warns the Israelites not to intermarry with the idolaters -the very idolaters who were supposed to be doomed!
A proper understanding, then, would view these passages as retrojections of what could and might have been, and the sentiments were acceptable in view of the common practices of the times.

Deuteronomy: The Traditional Hebrew Text with the New JPS Translation - Jeffrey H. TigayModern scholars hold that this law is purely theoretical and was never in effect. In their view, the populations of only a few Canaanite cities were annihilated, but most were not. There is much evidence in favor of this view. Archaeology has found only a few Canaanite cities that seem to have been destroyed by the Israelites when they arrived in the land at the beginning of the Iron Age (ca. 1200 B.C.E.). As noted above, pre-Deuteronomic laws, in Exodus, speak of the Canaanites being expelled rather than annihilated, and the narratives of Judges, Kings, and Joshua 15-17 indicate that many were neither expelled nor annihilated but were spared and subjected to forced labor.3 Some scholars suggest that even Deuteronomy did not originally require annihilating the Canaanites. In their view, Deuteronomy's original law consisted only of 20:10-14, according to which all cities are to be offered terms of submission. They note that Joshua 11:19,Joshua 15-17, and Judges all reflect this form of the law. In this view the following paragraph in Deuteronomy, verses 15-18, is a later supplement that modifies the original law by restricting the requirement to offer the option of surrender to foreign, non-Canaanite cities. This supplement is reflected in Deuteronomy 7:1-5, 16-26, and the narratives of Joshua 6-11 (except for Joshua 11:19-20), but it is based on a theoretical reconstruction, conceived at a later time when the Canaanites had ceased to exist as a discernible element of the population in Israel, to account for their disappearance.
If this is the case, where did the idea of proscribing the Canaanites come from? The historical books, as noted, indicate that the invading Israelites did proscribe some Canaanite cities. Proscription was a well-known practice in the ancient world. One type of proscription was the religious practice of devoting property, cattle, or persons (perhaps the victims of sacrificial vows, such as Jephthah's daughter) irrevocably to a deity, that is, to a sanctuary and the priests, sometimes by destruction or killing. Another type was punitive proscription, which consisted of executing those who committed severe offenses against the gods. This type is prescribed by Exodus 22:17 for individual idolaters, and by Deuteronomy 13:13-18for idolatrous cities. Proscription of enemy armies and populations to the gods is known from various places in the ancient world. King Mesha of Moab proscribed the Israelite inhabitants of some towns in Transjordan to his god when he recaptured former Moabite territory there. Other parallels are known from Mesopotamia and ancient Europe. In the context of ancient warfare, in which the gods were believed to be the main fighters and human antagonists their enemies, proscription of the enemy's population seemed to be a natural way for an army to express devotion to a deity. A case in point is God's command to Saul to proscribe the Amalekites to avenge their ancient ambush of the Israelites. Proscription was not considered necessary or obligatory in most cases, but was something that an army might vow to do to induce divine aid in critical circumstances, such as before a crucial battle or a counterattack following a defeat. Examples of this are Israel's proscription of Arad and Ai after initial defeats by them, and the proscription of Jericho at the start of Israel’s campaign for the promised land.
Deuteronomy appears to have inferred from cases like these that the disappearance of the Canaanites was due to a systematic policy of proscription. Aware that there were no discernible Canaanites left in Israel, aware from Exodus and Numbers that the land was to be rid of them, aware of Exodus 22:17,which requires proscription of Israelite idolaters, and mindful of its own law requiring proscription of idolatrous Israelite cities, Deuteronomy must have assumed that God, in His zeal to protect Israel from exposure to pagan abominations, had required eliminating the Canaanites by the same means. It is interesting, however, that Deuteronomy never speaks of proscribing the victims to God. It uses proscription in a purely secular way, meaning simply "destruction." It is not a sacrifice to God but a practical measure to prevent the debasement of Israelite conduct.
Traditional Jewish commentators, as mentioned, do not believe that Deuteronomy means to proscribe the Canaanites unconditionally. The Sifrei and other halakhic sources reason that since the express purpose of the law is to prevent the Canaanites from influencing the Israelites with their abhorrent religious practices (v. 18), if they abandoned their paganism and accepted the moral standards of the Noachide laws they were to be spared. Maimonides holds that verse 10 requires that Israel offer terms of surrender to all cities, Canaanite included. In his view, when verse 15says "thus you shall deal" with non-Canaanite cities, it is not referring to, and limiting, verse 10, but verse 14, which calls for sparing the women and children of a city taken in battle. In his view this means that all cities must be given the option of surrender; the difference between Canaanite and foreign cities is only that if foreign cities reject the offer, only their men are to be killed, but if Canaanite cities reject the offer, their entire population is to be killed. This view is compatible with Joshua 11:19,which implies that Canaanite cities could have saved themselves by surrendering: "Not a single city made terms [hishlimah] with the Israelites; all were taken in battle."
These arguments notwithstanding, it is clear from 7:1-2 and 16 that Deuteronomy's demand for proscription of the Canaanites is indeed unconditional. The rabbis' rejection of this view is a reflection of their own sensibilities. As M. Greenberg has observed, they must have regarded this understanding of the law as implausible because it is so harsh and inconsistent with other values, such as the prophetic concept of repentance and the prediction that idolaters will someday abandon false gods, and the halakhic principle that wrongdoers may not be punished unless they have been warned that their action is illegal and informed of the penalty. In effect, they used interpretation to modify and soften the law in deference to other, overriding principles.
