申命記 20:17的塔木德參照：Jerusalem Talmud Avodah Zarah

HALAKHAH: “An idol which was abandoned by its worshippers,” etc. It was stated: The war of Joshua is forbidden, similar to the war of Joshua is permitted. The war of David is permitted, like the war of David is forbidden. The war of Joshua is forbidden, as it is written⁹⁹Deut. 20:17. This verse is quoted as justification of the first statement, that idols captured in the wars of Joshua were forbidden., for certainly you should ban them. Similar to the war of Joshua is permitted, for it is a short time¹⁰⁰Idols conquered in a war of limited duration are temporarily forbidden until it is ascertained after the war that no worshippers returned, as in the war of Joshua where in theory all Canaanites were killed (Deut. 20:16).. The war of David is permitted, what Itai from Gat annulled¹⁰¹Since David had Gentile mercenaries in his army, they immediately could annul all idols and articles of pagan worship which then became of use (Chapter 3:3 Note 108).. Like the war of David is forbidden, for it is permanent¹⁰²If a war is not ended with a peace but with an indefinite truce, the preceding arguments are not applicable..
