2 Samuel 7:14

I will be his father, and he shall be my son: and I will not take my mercy away from him, as I took it from him that was before thee:

And he said unto me, Solomon thy son, he shall build my house and my courts: for I have chosen him to be my son, and I will be his father.

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 lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.

For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
