Psalm 89v29-37

²⁹ I will also make his offspring endure forever,
    and his throne as the days of heaven.
³⁰ If his children forsake my law,
    and don’t walk in my ordinances;
³¹ if they break my statutes,
    and don’t keep my commandments;
³² then I will punish their sin with the rod,
    and their iniquity with stripes.
³³ But I will not completely take my loving kindness from him,
    nor allow my faithfulness to fail.
³⁴ I will not break my covenant,
    nor alter what my lips have uttered.
³⁵ Once I have sworn by my holiness,
    I will not lie to David.
³⁶ His offspring will endure forever,
    his throne like the sun before me.
³⁷ It will be established forever like the moon,
    the faithful witness in the sky.” Selah.
