1 Samuel 18:3-5

New Living Translation

³ And Jonathan made a solemn pact with David, because he loved him as he loved himself. ⁴ Jonathan sealed the pact by taking off his robe and giving it to David, together with his tunic, sword, bow, and belt.

⁵ Whatever Saul asked David to do, David did it successfully. So Saul made him a commander over the men of war, an appointment that was welcomed by the people and Saul’s officers alike.
