Jewish Captives, Cruelty, & Compassion
Jewish law on the proper treatment of prisoners of war
Classical Jewish law offers a decidedly ambivalent view of both war and punishment. Both of these categories are presented as necessary evils that must be approached with caution. Virtually every mention of war in the Bible and later sources is accompanied by warnings against certain types of behavior, and the laws of punishment include numerous checks against unfair or excessive punishment.
Biblically Mandated Wars
Jewish law does not specifically recognize the category of "prisoner of war" and therefore does not establish conditions governing the treatment of such prisoners. This omission may be attributed largely to the fact that, in the absence for most of history of a Jewish sovereign state, the laws of warfare--like most areas of Jewish civil law--never developed to the extent that ritual laws did. Furthermore, the wars mandated by the Bible, against specific groups of enemies at specific times, require the killing of all of the men and, in some cases, the women. While disturbing to many people today, this requirement probably reflects a fear that the Jews will be negatively influenced by the customs of the conquered.
At least one contemporary Jewish legal scholar has argued that the biblical mandate to kill all combatants is no longer applicable. According to Rabbi Shlomo Goren, the Ashkenazic chief rabbi of Israel from 1973-1983 and the chief rabbi of the Israel Defense Forces in the 1950s and 1960s:
"[Regarding] those obligatory wars that we were explicitly commanded by the Torah to wage in antiquity, in which 'you shall not let a soul remain alive'--one must not learn from them, heaven forbid, about other wars and our own time… We are commanded by the Torah to follow in God's ways and to have compassion for God's creatures, as it is written: 'God's mercy is upon all God's works' (Psalms 145:9)" (Meshiv Milhama vol. 1, p. 14).
Treatment of Captives
Even without a specific discussion of the treatment of POWs, we can extrapolate from other statements about battlefield ethics and appropriate punishments some general principles about the treatment of opponents during a war and, in particular, about opponents judged to be criminals deserving of legal punishment.
A few statements within the Bible itself prohibit excessive cruelty during times of war. In particular, while permitting soldiers to take women as captives, the Bible tempers this permission, saying:
"When you take the field against your enemies and Adonai your God delivers them into your power and you take some of them captive, and you see among the captives a beautiful woman and you desire her and would take her to wife, you shall bring her into your house, and she shall trim her hair, pare her nails, and discard her captive's garb. She shall spend a month's time in your house lamenting her father and mother; after that you may come to her and possess her, and she shall be your wife. Then, should you no longer want her, you must release her outright. You must not sell her for money: since you had your will of her, you must not enslave her" (Deuteronomy 21:10-15).
