1 Chronicles 12:16-18

16Other Benjaminites and men from Judah also went to David at the stronghold.

17David went out to meet them and said to them, “If you have come in peace to help me, my heart will be united with you, but if you have come to betray me to my enemies even though my hands have done no wrong, may the God of our ancestors look on it and judge.”

18Then the Spirit enveloped Amasai, chief of the Thirty, and he said: We are yours, David, we are with you, son of Jesse! Peace, peace to you, and peace to him who helps you, for your God helps you. So David received them and made them leaders of his troops.
