Proverbs 24:17-18 English Standard Version (ESV)
17 Do not rejoice when your enemy falls,
and let not your heart be glad when he stumbles,
18 lest the Lord see it and be displeased,
and turn away his anger from him.
Proverbs 24:17-18 New International Version (NIV)
17 Do not gloat when your enemy falls;
when they stumble, do not let your heart rejoice,
18 or the Lord will see and disapprove
and turn his wrath away from them.
