his throne forever
1 Chronicles 17:12 He shall build me an house, and I will stablish his throne for ever.
13 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:
Luke 1:32 He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David:
33 And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
