a Bible passage
foot … hand—The humble speaks of the more honorable member which most nearly resembles itself: so the "ear" of the "eye" (the nobler and more commanding member, Nu 10:31), (1Co 12:16). As in life each compares himself with those whom he approaches nearest in gifts, not those far superior. The foot and hand represent men of active life; the ear and eye, those of contemplative life.
