Psalm 89:27-37

27And I will appoint him to be my firstborn, the most exalted of the kings of the earth.

28I will maintain my love to him forever, and my covenant with him will never fail.

29I will establish his line forever, his throne as long as the heavens endure.

30“If his sons forsake my law and do not follow my statutes,

31if they violate my decrees and fail to keep my commands,

32I will punish their sin with the rod, their iniquity with flogging;

33but I will not take my love from him, nor will I ever betray my faithfulness.

34I will not violate my covenant or alter what my lips have uttered.

35Once for all, I have sworn by my holiness— and I will not lie to David—

36that his line will continue forever and his throne endure before me like the sun;

37it will be established forever like the moon, the faithful witness in the sky.”
