LEV789 No less than thirty-six times does the Torah remind us of our special obligation to the alien or stranger (Bava Metzia 39b) [this and following verse]. Indeed the ultimate source of the universality of Torah morality is to be found in the synthesis of two metaphysical beliefs: first, the unity of mankind as fixed by a common ancestry in Adam and a common nature grounded in the "image God"; second, a vision of the redemption that will encompass all mankind: "For then I will turn to the peoples a pure language that they may call upon the name of the Lord to serve Him with one consent." (Zephaniah 3:9. See also Isaiah 56:1-7 and 66: 18-21).
