1 Samuel 16:13-15

AKJV(i) 13 Then Samuel took the horn of oil, and anointed him in the middle of his brothers: and the Spirit of the LORD came on David from that day forward. So Samuel rose up, and went to Ramah. 14 But the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him. 15 And Saul's servants said to him, Behold now, an evil spirit from God troubles you.
