Psalm 89:28; Psalm 89:35-37

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