like the moon
Psalm 89:19-37 (JDV)
Psalm 89:19 You once spoke in a vision to your covenant devotees and said: “I have granted help to a warrior; I have lifted high someone chosen from the people.
Psalm 89:20 I have found David my servant; I have anointed him with my sacred oil.
Psalm 89:21 My hand will always be with him, and my arm will strengthen him.
Psalm 89:22 The enemy will not oppress him; the wicked will not afflict him.
Psalm 89:23 I will crush his foes before him and strike those who hate him.
Psalm 89:24 My reliability and covenant faithfulness will be with him, and through my name his horn will be lifted high.
Psalm 89:25 I will extend his power to the sea and his right hand to the rivers.
Psalm 89:26 He will call to me, ‘You are my Father, my God, the rock of my deliverance.’
Psalm 89:27 I will also make him my firstborn, greatest of the kings of the land.
Psalm 89:28 I will permanently preserve my covenant faithfulness for him, and my covenant with him will endure.
Psalm 89:29 I will establish his line forever, his throne as long as sky lasts.
Psalm 89:30 If his sons abandon my instruction and do not walk by what I judge,
Psalm 89:31 if they dishonor my prescriptions and do not keep my commands,
Psalm 89:32 then I will call their rebellion to account with the rod, their iniquity with blows.
Psalm 89:33 But I will not withdraw my covenant faithfulness from him or betray my reliability.
Psalm 89:34 I will not violate my covenant or change what my lips have said.
Psalm 89:35 Once and for all I have sworn an oath by my sacredness; I will not lie to David.
Psalm 89:36 His offspring will continue permanently, his throne like the sun before me,
Psalm 89:37 like the moon, established permanently, a faithful witness in the sky.” Selah
like the moon
The moon does not always appear in the sky, but it is there. God compared his faithfulness to David with the moon. It waxes and wanes. It is sometimes full, sometimes partial — invisible when it is “new” — but that moon is always there. This is a wonderful simile describing God’s faithfulness to his chosen king.
