1 Samuel 18:3-5

Amplified Bible, Classic Edition

³ Then Jonathan made a covenant with David, because he loved him as his own life.

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

⁵ And David went out wherever Saul sent him, and he prospered and behaved himself wisely; and Saul set him over the men of war. And it was satisfactory both to the people and to Saul’s servants.
