“And David came to Saul, and stood before him: and he loved him greatly; and he became his armourbearer.”
King James Version (KJV)
16:21 Stood before him - That is, waited upon him. And he loved him greatly - So there was something good in Saul still: he had not lost all, tho' he had lost the kingdom. Armour - bearer - He had that place conferred upon him, though we do not read that he ever exercised it; for it seems he was gone back to his father upon some occasion not related; and had abode with him some considerable time before the war described, chap.#17:1 |- 53, happened.
