21. DAVID came to Saul, and stood before him. He loved him greatly; and he became his armor bearer.
22. Saul sent to Jesse, saying, "Please let DAVID stand before me; for he has found favor in my sight."
23. When the spirit from God was on Saul, DAVID took the harp, and played with his hand; so Saul was refreshed, and was well, and the evil spirit departed from him.
DAVID spoke to the chief of the Levites to appoint their brothers as singers with instruments of music, stringed instruments, harps, and cymbals, sounding aloud and lifting up their voices with joy.
four thousand were doorkeepers, and four thousand praised the LORD with the instruments which I made for giving praise."
