Psalms 89:35LXX

33Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail.

34My covenant will I not break, nor alter the thing that is gone out of my lips.

35Once have I sworn by my holiness that I will not lie unto David.

36His seed shall endure for ever, and his throne as the sun before me.

37It shall be established for ever as the moon, and a faithful witness in heaven. Selah.
