Yahweh said to Samuel, How long will you mourn for Saul, seeing I have rejected him from being king over Israel? fill your horn with oil, and go: I will send you to Jesse the Bethlehemite; for I have provided me a king among his sons.
and go, and I will send thee to Jesse the Bethlehemite; the son of Obed, whom Boaz begat of Ruth the Moabitess, Ruth 4:21
