1 Samuel 16:20-22

20So Jesse took some loaves of bread, a bag with wine in it, and a young goat. He put them on the back of a donkey and he sent them to Saul with his son David.

21David went to Saul. He became Saul's servant. Saul loved David. David carried Saul's armour for him.

22Then Saul sent a message to Jesse. He said, ‘I am very pleased with David. Let him stay here as my servant.’
