1 Samuel 16

11 Then Samuel asked, "Are these all the sons you have?"

"There is still the youngest," Jesse replied. "But he’s out in the fields watching the sheep and goats."

"Send for him at once," Samuel said. "We will not sit down to eat until he arrives."

13 So as David stood there among his brothers, Samuel took the flask of olive oil he had brought and anointed David with the oil. And the Spirit of the Lord came powerfully upon David from that day on. Then Samuel returned to Ramah.
