'Helpers' in the Bible

These are the ones who came to David at Ziklag, while he still concealed himself from Saul the son of Kish; they were among the courageous men who helped him in battle.

Then the [Holy] Spirit came on Amasai, who was chief of the thirty, and he said,“We are yours, O David,And with you, O son of Jesse!Peace, peace be to you,And peace be to him who helps you;For your God helps you.” Then David accepted and received them and made them officers of his troops.
