1 Samuel 13:14

And when he had removed him, he raised up unto them David to be their king; to whom also he gave testimony, and said, I have found David the son of Jesse, a man after mine own heart, which shall fulfil all my will.

And Samuel said unto him, The Lord hath rent the kingdom of Israel from thee this day, and hath given it to a neighbour of thine, that is better than thou.

Then thou spakest in vision to thy holy one, and saidst, I have laid help upon one that is mighty; I have exalted one chosen out of the people. I have found David my servant; with my holy oil have I anointed him: With whom my hand shall be established: mine arm also shall strengthen him. The enemy shall not exact upon him; nor the son of wickedness afflict him. And I will beat down his foes before his face, and plague them that hate him. But my faithfulness and my mercy shall be with him: and in my name shall his horn be exalted. I will set his hand also in the sea, and his right hand in the rivers. He shall cry unto me, Thou art my father, my God, and the rock of my salvation. Also I will make him my firstborn, higher than the kings of the earth. My mercy will I keep for him for evermore, and my covenant shall stand fast with him. His seed also will I make to endure for ever, and his throne as the days of heaven. If his children forsake my law, and walk not in my judgments; If they break my statutes, and keep not my commandments; Then will I visit their transgression with the rod, and their iniquity with stripes. Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail. My covenant will I not break, nor alter the thing that is gone out of my lips. Once have I sworn by my holiness that I will not lie unto David. His seed shall endure for ever, and his throne as the sun before me. It shall be established for ever as the moon, and as a faithful witness in heaven. Selah.

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 Beth–lehemite: for I have provided me a king among his sons.

He chose David also his servant, and took him from the sheepfolds:

Who found favour before God, and desired to find a tabernacle for the God of Jacob.

And he sent, and brought him in. Now he was ruddy, and withal of a beautiful countenance, and goodly to look to. And the Lord said, Arise, anoint him: for this is he.

Wherefore the Lord God of Israel saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now the Lord saith, Be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed.

To morrow about this time I will send thee a man out of the land of Benjamin, and thou shalt anoint him to be captain over my people Israel, that he may save my people out of the hand of the Philistines: for I have looked upon my people, because their cry is come unto me.

Turn again, and tell Hezekiah the captain of my people, Thus saith the Lord, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will heal thee: on the third day thou shalt go up unto the house of the Lord.

Also in time past, when Saul was king over us, thou wast he that leddest out and broughtest in Israel: and the Lord said to thee, Thou shalt feed my people Israel, and thou shalt be a captain over Israel.

But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee. And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever.

For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings.
