The answer is: Psalms

Ps 59:8

Those who have read the Book of Psalms will agree it’s a treasure trove of emotions—from deep sorrow to exuberant joy. Now, imagine divine laughter echoing through the heavens just as laughter ripples through a gathering of friends! Feast your eyes on Psalm 59:8, where the psalmist vividly describes God laughing—specifically at the arrogance of the enemies prowling about. It’s a moment that juxtaposes human attempts at power with the upper hand of divine oversight. A delightful reminder that no matter how serious things might seem on earth, Heaven seems to chuckle at the folly of those who oppose justice or righteousness.

Interestingly, laughter in the ancient world often signified not just joy but also a kind of mockery or derision. The mention of God laughing here underlines a comforting truth: while people can create chaos with their machinations, there's a divine order that holds steady above it all. If you dive deeper into the Scriptures, you’ll find echoes of this divine laughter — Job 5:22 brings the concept into play, mentioning the fear of disaster while interpreting it against the backdrop of God’s omniscience.

And would you believe laughter pops up elsewhere in biblical history? Consider Sarah in Genesis, who laughed at the thought of bearing a child in her old age. God’s reactions to humans imbuing sacred moments with humanity remind us that even in worship or trials, joy peeks through the tapestry of faith.
