Compare chs. 49:23; 61:6; 66:12. Upon leaving Egypt the children of Israel were to receive gifts from their erstwhile masters (see on Ex. 3:22). Upon their return from Babylonian captivity the Jews received voluntary gifts of silver and gold from their neighbors and friends, and also from the royal treasury (Ezra 1:6; 7:15, 16, 21-23).
