1 Samuel 16:1

1The Lord said to Samuel, “How long will you grieve for Saul, when I have rejected him as king over Israel? 16:1 Samuel’s horn was a receptacle for olive oil, which he would use to anoint a new king.Fill your horn with oil and go; I will send you to Jesse the Bethlehemite, for I have chosen a king for Myself among his sons.”
