Like the moon it shall be established forever, a faithful witness in the skies.” Selah
English Standard Version (ESV)
While the moon is a clear image of lasting time, calling it a "faithful witness" hints that it testifies not just to the passage of days, but specifically to God's covenant, much like the rainbow. This highlights how even the celestial bodies serve as constant reminders of God's promises and his enduring faithfulness to his people.
Like the moon it shall be established forever, a faithful witness in the skies.” Selah
English Standard Version (ESV)
This verse comes at the climax of a long discourse where God, through the psalmist, reaffirms His unbreakable covenant with David's lineage, even amidst human failure and suffering. Despite potential disobedience from David's descendants, God pledges His steadfast love will not fail, His covenant will endure, and His promises will stand. The imagery of the sun and moon, and the faithful witness, emphasizes the eternal and unwavering nature of this divine commitment to David's dynasty.
The psalmist uses the moon to describe the enduring nature of God's promises. But the moon changes, waxes and wanes. How can it represent permanence?
A Witness Through Change
The psalmist declares, 'It shall be established for ever as the moon.' This is a powerful image! At first glance, it might seem odd because the moon constantly changes – from a sliver to a full orb and back again. Yet, the moon's very cycle of change is precisely what makes it a constant, predictable presence.
Think about it:
In the same way, God's covenant with David, and by extension His promises to us through Christ, are established forever. Though circumstances change, and we ourselves go through 'phases,' God's faithfulness remains. His covenant isn't dependent on our perfect performance but on His unwavering character.
The verse calls the moon 'a faithful witness in the skies.' What exactly is it witnessing to, and why is that important for us today?

Bearing Witness to God's Promises
The psalmist adds that this enduring sign is 'a faithful witness in the heavens.' This 'witness' is deeply connected to God's covenant. The celestial bodies, particularly the moon and sometimes the rainbow (as mentioned in commentaries), served as visible signs of God's promises.
What does this witness declare?
This 'faithful witness' isn't just for the ancient Israelites; it's a message for us. In a world often marked by inconsistency and broken promises, God's faithfulness, declared in the very fabric of creation, offers a profound assurance of His love and commitment.

(37) And as a faithful witness in heaven. —Rather, and there is a faithful witness in heaven, which the parallelism shows to be the moon, just mentioned. The moon (see Psalm 81:3 ) was to the Jews—as to the ancients generally—the “arbiter of festivals,” and the festivals were signs of the covenant, consequently that luminary might well be called “a witness in heaven.”
