“I will establish his line forever.
I will establish his throne as long as the heavens endure.
If his children forsake my law,
If they do not walk according to my ordinances,
If they violate my statutes,
If they do not keep my commandments,
Then I will punish their transgression with the rod.
I will punish their iniquity with scourges.
But I will not remove from him my steadfast love.
I will not be false to my faithfulness.
I will not violate my covenant.
I will not alter the word that went forth from my lips.
Once and for all
I have sworn by my holiness.
I will not lie to David.
His line shall continue forever.
His throne shall endure before me like the sun.
It shall be established forever like the moon.
It shall be an enduring witness in the skies.”
The throne of David is not just for him, but his descendants. His line of descendants will last until the heavens disappear. However, this is not an unconditional gift. There are conditions. If his children do certain things they will receive the rod and be scourged. They should not forsake God’s law. They have to walk according to his ordinances. They cannot violate his statutes. They should keep his commandments. This punishment to those who do not follow the laws and ordinances will not be permanent. They will always have the steadfast love of God and his covenant. God would keep his word that he gave to David. He would not lie. The line of David will continue forever just like the sun and the moon in the skies. This section ends with the musical interlude meditative pause of Selah.
