After another period of ten days, which he spent in retirement with his hosts, Joab sallied forth a second time, and caused such bloodshed among the Amalekites that his gory weapon clave to his hand, and his right hand lost all power of independent motion, it could be made to move only in a piece with his arm. He hastened to his lodging place to apply hot water to his hand and free it from the sword. On his way thither the woman who had caught him up when he fell into the city called to him: "Thou eatest and drinkest with us, yet thou slayest our warriors." Seeing himself betrayed, he could not but kill the woman. Scarcely had his sword touched her, when it was separated from his hand, and his hand could move freely, for the dead woman had been with child, and the blood of the unborn babe loosed the sword. After Joab had slain thousands, the Israelites without, at the very moment when they were beginning to mourn their general as dead, saw blood issue from the city, and joyfully they cried out with one accord: "Hear, O Israel, the Lord is our God, the Lord is One." Joab mounted a high tower, and in stentorian tones shouted: "The Lord will not forsake his people." Inspired with high and daring courage, the Israelites demanded permission to assault the city and capture it. As Joab turned to descend from the tower, he noticed that six verses of a Psalm were inscribed on his foot, the first verse running thus: "The Lord answers thee in the day of trouble, the name of the God of Jacob is thy defense." Later David added three verses and completed the Psalm. Thereupon the Israelites took the Amalekite capital, destroyed the heathen temples in the city, and slew all its inhabitants, except the king, whom, with his crown of pure gold on his head, they brought before David. (77) DAVID'S PIETY AND HIS SIN Neither his great achievements in war nor his remarkable good fortune moved David from his pious ways, or in aught changed his mode of life. Even after he became king he sat at the feet of his teachers, Ira the Jairite (78) and Mephibosheth. To the latter he always submitted his decisions on religious questions, to make sure that they were in accordance with law. (79) Whatever leisure time his royal duties afforded him, he spent in study and prayer. He contented himself with "sixty breaths" of sleep. (80) At midnight the strings of his harp, (81) which were made of the gut of the ram sacrificed by Abraham on Mount Moriah, (82) began to vibrate. The sound they emitted awakened David, and he would arise at once to devote himself to the study of the Torah. (83)
