A king of flesh and blood, whilst at war, cannot supply all of his soldiers. Not so, the Holy One Blessed be He. "The L–rd is a man of war" — He wars against Egypt. "The L–rd is His name" — He sustains all who enter the world. As it is written (Psalms 136:13) "He divides the sea into strips" (twelve strips for twelve tribes) — (Ibid. 25) "He gives bread to all flesh." (Ibid. 147:10) He gives the beast its food, the raven's young, what they call for."
