Noah realized that he had been guilty of folly. To propitiate God and acknowledge his sin, he brought a sacrifice. God accepted the offering with favor, whence he is called by his name Noah. The sacrifice was not offered by Noah with his own hands; the priestly services connected with it were performed by his son Shem. There was a reason for this. One day in the ark Noah forgot to give his ration to the lion, and the hungry beast struck him so violent a blow with his paw that he was lame forever after, and, having a bodily defect, he was not permitted to do the offices of a priest.
