In the solitude of the desert David had opportunities of displaying his extraordinary physical strength. One day he slew four lions and three bears, though he had no weapons. His most serious adventure was with the reem. David encountered the mammoth beast asleep, and taking it for a mountain, he began to ascend it. Suddenly the reem awoke, and David found himself high up in the air on its horns. He vowed, if he were rescued, to build a temple to God one hundred ells in height, as high as the horns of the reem. Thereupon God sent a lion. The king of beasts inspired even the reem with awe. The reem prostrated himself, and David could easily descend from his perch. At that moment a deer appeared. The lion pursued after him, and David was saved from the lion as well as the reem.
