GEN1078 It was taught: “R. Chiyya b. Abba said in the name of R. Yochanan: Whence do we derive that the Holy One Blessed be He does not withhold reward even for discretion in the use of words?   For in relation to the elder daughter, who called her son ‘Moav’ [lit., ‘from my father’], the Holy One Blessed be He commanded Deuteronomy 2:9: ‘Do not besiege Moav, not incite a war against them’ – it is not permitted to war against them, but it is permitted to subjugate them; whereas in relation to the younger daughter who called her son [euphemistically] ‘Ben Ami’ [‘son of my nation’], the Holy One Blessed be He commanded Moses Deuteronomy 2:19: ‘Do not besiege them [Ammon] and do not incite them [at all]’ – it is not even permitted to subjugate them” Nazir 23a TEMIMAH-GEN 92-93
