Then the Spirit came on Amasai, who was chief of the thirty, [and he said], "We are yours, David, and on your side, you son of Jesse: peace, peace be to you, and peace be to your helpers; for your God helps you." Then David received them, and made them captains of the band.
In view of his readers’ assumed knowledge, the Chronicler makes no attempt to record events that have little to do with his central purpose. For example, he omits all reference to the attempt by Saul’s followers to continue the rule of Saul’s family (2 Samuel 1:1-12). Instead he passes straight on to the establishment of David in Jerusalem as king over all Israel (11:1-9; see notes on 2 Samuel 5:1-10), and the important part that David’s mighty men played in establishing and maintaining his kingdom (10-47; see notes on 2 Samuel 23:8-39).
