EXOD797 Personal dislikes and animosities do not affect one's social obligations to his fellow man. This rule is expressed forcefully in the Book of Proverbs: "If thy enemy is hungry give him bread to eat, and if he is thirsty give him water to drink" (Proverbs 25:21). All biblical social commands are applicable to friend and foe alike [this and following verses]. The temptation to disregard an enemy in need is very intense. Indeed it requires much character training to ignore one's normal inclination to look the other way. To emphasize the urgency of such character training, the rabbis promulgated an amendment to an established law: "If a friend requires unloading [of an animal which has fallen because the burden was too heavy for it--normally such an obligation has priority], and an enemy requires loading, one's [prior] obligation is toward his enemy, in order to subdue his evil inclination" [to offer no help to an enemy] (Baba Metzia 32b).
