Besides study, the composition of psalms naturally claimed a goodly portion of his time. Pride filled his heart when he had completed the Psalter, and he exclaimed: "O Lord of the world, is there another creature in the universe who like me proclaims thy praise?" A frog came up to the king, and said: "Be not so proud; I have composed more psalms than thou, and, besides, every psalm my mouth has uttered I have accompanied with three thousand parables." And, truly, if David indulged in conceit, it was only for a moment. As a rule he was the exemplar of modesty. The coins which were stamped by him bore a shepherd's crook and pouch on the obverse, and on the reverse the Tower of David. In other respects, too, his bearing was humble, as though he were still the shepherd and not the king.
