Psalm 89:30-37 NIV

[30] “If his sons forsake my law and do not follow my statutes, [31] if they violate my decrees and fail to keep my commands, [32] I will punish their sin with the rod, their iniquity with flogging; [33] but I will not take my love from him, nor will I ever betray my faithfulness. [34] I will not violate my covenant or alter what my lips have uttered. [35] Once for all, I have sworn by my holiness—and I will not lie to David— [36] that his line will continue forever and his throne endure before me like the sun; [37] it will be established forever like the moon, the faithful witness in the sky.”
