1 Chronicles 12:18; 1 Chronicles 12:21
Then the Spirit came upon Amasai, chief of the Thirty, and he said: "We are yours, O David! We are with you, O son of Jesse! Success, success to you, and success to those who help you, for your God will help you." So David received them and made them leaders of his raiding bands.
They helped David against raiding bands, for all of them were brave warriors, and they were commanders in his army.
