"King David"
13:13 And Samuel said to Saul, Thou hast done foolishly: thou hast not kept the commandment of the LORD thy God, which he commanded thee: for now would the LORD have established thy kingdom upon Israel for ever.
13:14 But now thy(Saul's) kingdom shall not continue: the LORD hath sought him a man(David) after his own heart, and the LORD hath commanded him to be captain over his people, because thou hast not kept that which the LORD commanded thee.

Chapter 16
16:1 And the LORD said unto Samuel, How long wilt thou mourn for Saul, seeing I have rejected him from reigning over Israel? fill thine horn with oil, and go, I will send thee to Jesse the Bethlehemite: for I have provided me a king among his sons.

16:13 Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the spirit of the LORD came upon David from that day forward. So Samuel rose up, and went to Ramah.
16:14 But the spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him.
