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.
Many of these men of Benjamin and Judah, in the first place, went to join themselves to David because  they had heard that he was the Lord's anointed . They understood that Samuel had gone down to Ramah, and, in the days of David's youth, had anointed him in the name of the Lord to be king instead of Saul. Therefore they said, “Whom God anoints we will follow,” and they came after David. It was fit that they should be loyal to David if they would be obedient to God.
