Job was dear to God, perfect and upright before Him; Job 2:3 yet hear what he says of the devil: His strength is in the loins, and his force is in the navel. The terms are chosen for decency's sake, but the reproductive organs of the two sexes are meant. Thus, the descendant of David, who, according to the promise is to sit upon his throne, is said to come from his loins. And the seventy-five souls descended from Jacob who entered Egypt are said to come out of his thigh. Genesis 46:26 So, also, when his thigh shrank after the Lord had wrestled with him, Genesis 32:24-25 he ceased to beget children. The Israelites, again, are told to celebrate the passover with loins girded and mortified. Exodus 12:11 God says to Job: Gird up your loins as a man. Job 38:3 John wears a leathern girdle. Matthew 3:4 The apostles must gird their loins to carry the lamps of the Gospel. Luke 12:35 When Ezekiel tells us how Jerusalem is found in the plain of wandering, covered with blood, he uses the words: Your navel has not been cut. Ezekiel 16:4-6 In his assaults on men, therefore, the devil's strength is in the loins; in his attacks on women his force is in the navel.
