His plan was executed. Joab took with him one thousand pieces of money and his sword. When he was cast from the sling, he fell into the courtyard of a widow, whose daughter caught him up. In a little while he regained consciousness. He pretended to be an Amalekite taken prisoner by the Israelites, and thrown into the city by his captors, who thus wished to inflict death. As he was provided with money, which he dispensed lavishly among his entertainers, he was received kindly, and was given the Amalekite garb. So apparelled, he ventured, after ten days, on a tour of inspection through the city, which he found to be of enormous size.
