Psalm 89:30-37 GNT

30 "But if his descendants disobey my law and do not live according to my commands,
31 if they disregard my instructions and do not keep my commandments,
32 then I will punish them for their sins; I will make them suffer for their wrongs.
33 But I will not stop loving David or fail to keep my promise to him.
34 I will not break my covenant with him or take back even one promise I made him.
35 "Once and for all I have promised by my holy name: I will never lie to David.
36 He will always have descendants, and I will watch over his kingdom as long as the sun shines.
37 It will be as permanent as the moon, that faithful witness in the sky."
