"The righteous also will see it, and fear, and laugh at him" (52:6). Is it right to laugh when someone falls?

The psalm says what the righteous do and what they say. They "will see it, and fear, and laugh at him" (52:6), and what they say is about where the man put his strength and his trust: "this is the man who didn’t make God his strength, but trusted in the abundance of his riches" (52:7). Their fear comes before their laughing. Other verses speak of an enemy's fall in another way: "Don’t rejoice when your enemy falls. Don’t let your heart be glad when he is overthrown" (Proverbs 24:17). And in other psalms it is God who laughs, with the same Hebrew verb as 52:6: "He who sits in the heavens will laugh" (Psalm 2:4), "The Lord will laugh at him, for he sees that his day is coming" (Psalm 37:13), and "But you, LORD, laugh at them" (Psalm 59:8). These verses stand side by side in Scripture, and these notes don't choose how they fit together.
