1 Samuel 18:3-5

Amplified Bible

³ Then Jonathan made a covenant with David because he loved him as himself. ⁴ Jonathan stripped himself of the outer robe that he was wearing and gave it to David, with his armor, including his sword, his bow, and his belt. ⁵ So David went out wherever Saul sent him, and he acted wisely and prospered; and Saul appointed him over the men of war. And it pleased all the people and also Saul’s servants.
