Thus, Jesse made seven of his sons pass before Samuel, butSamuel told him, “The LORD has not chosen any of these.”And Samuel asked him, “Are these all the sons you have?”“There is still the youngest,” Jesse replied, “but he is tending the sheep.”“Send for him,” Samuel replied. “For we will not sit down to eat until he arrives.”So Jesse sent for his youngest son and brought him in.
-Samuel picks his servant- 16:10-12
-Samuel Anoints David- 16:12-13
Jesse sent for his youngest son and brought him in. He was ruddy, with beautiful eyes and a handsome appearance.
So Samuel took the horn of oil and anointed him in the presence of his brothers, and the Spirit of the LORD rushed upon David from that day forward. Then Samuel set out and went to Ramah.
21When David came to Saul and entered his service, Saul admired him greatly, 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.” 23And whenever the spirit from God came upon Saul, David would pick up his harp and play, and Saul would become well, and the spirit of distress would depart from him.
