1 Samuel 18:3-5

Darby Translation

³ And Jonathan and David made a covenant, because he loved him as his own soul.

⁴ And Jonathan stripped himself of the robe that was upon him, and gave it to David, and his dress, even to his sword, and to his bow, and to his girdle.

⁵ And David went forth; whithersoever Saul sent him he prospered; and Saul set him over the men of war, and he was accepted in the sight of all the people, and also in the sight of Saul's servants.
