Albert Barnes Commentary Proverbs 24:18

"Lest Jehovah see it, and it displease him, And he turn away his wrath from him." — Proverbs 24:18 (ASV)

The meaning is, “Your joy will be suicidal; the wrath of the righteous Judge will be turned upon you, as the greater offender, and you will have to bear a worse evil than that which you exult in.”
