1 Samuel 18:2-6

And Saul took him that day and did not let him return to his father’s house.

Then Jonathan made a covenant with David because he loved him as himself.

Jonathan stripped himself of the robe that was on him and gave it to David, with his military gear, including his sword, his bow, and his belt.

And David went into battle wherever Saul sent him, and always achieved success; so Saul put him in charge of the men of war. And it was pleasing in the sight of all the people, and also in the sight of Saul’s servants.

Now it happened as they were coming, when David returned from killing the Philistine, that the women came out of all the cities of Israel, singing and dancing, to meet King Saul, with tambourines, with joy and with other musical instruments.
