1 Samuel 18:5 (KJV)

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

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

And David went out whithersoever Saul sent him, and behaved himself wisely: 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.

And it came to pass as they came, when David was returned from the slaughter of the Philistine, that the women came out of all cities of Israel, singing and dancing, to meet king Saul, with tabrets, with joy, and with instruments of musick.

And the women answered one another as they played, and said, Saul hath slain his thousands, and David his ten thousands.
