כִּֽי־תִקְרַ֣ב אֶל־עִ֔יר לְהִלָּחֵ֖ם עָלֶ֑יהָ וְקָרָ֥אתָ אֵלֶ֖יהָ לְשָׁלֽוֹם׃
Quand tu marcheras sur une ville pour l’attaquer, tu l’inviteras d’abord à la paix.
Tractate Derekh Eretz Zuta
R. Jose the Galilean said: Great is peace, since even in a time of war one should begin [by attempting to arrange] peace, as it is stated, When thou drawest nigh unto a city to fight against it, then proclaim peace unto it.49Deut. 20, 10.
