Rabbi Hiyya bar Abba, citing Rabbi Johanan, taught that God rewards even polite speech. In , Lot's older daughter named her son Moab ("of my father"), and so in , God told Moses, "Be not at enmity with Moab, neither contend with them in battle"; God forbade only war with the Moabites, but the Israelites might harass them. In , in contrast, Lot's younger daughter named her son Ben-Ammi (the less shameful "son of my people"), and so in , God told Moses, "Harass them not, nor contend with them"; the Israelites were not to harass the Ammonites at all.
