1 Samuel 16:20-22

20And Jesse took a donkey loaded with bread, a skin of wine, and one young goat and sent them to Saul with his son David. 21When David came to Saul and entered his service, Saul loved him very much, and David became his armor-bearer.

22Then Saul sent word to Jesse, saying, “Let David remain in my service, for I am pleased with him.”
