18 But a spirit empowered Amasai, the leader of the group of warriors known as the Thirty, and he said: “We are yours, O David! We support you, O son of Jesse! May you greatly prosper. May those who help you prosper. Indeed your God helps you!” So David accepted them and made them leaders of raiding bands.
Darby
18 And the Spirit came upon Amasai, the chief of the captains, [and he said,] Thine [are we], David, And with thee, thou son of Jesse: Peace, peace be to thee! And peace be to thy helpers! For thy God helps thee. And David received them, and made them chiefs of bands.
