Vengeance belongs to God:

God says not to retaliate – Leviticus 19:18
Moses proclaiming God’s words – Deuteronomy 32:35
God controls who gets His wrath – Proverbs 24:17, – Proverbs 24:18
God will give what is deserved – Proverbs 24:29
Paul speaking of gifts – Romans 12:19
Paul speaking on God’s sole prerogative – Hebrews 10:30
Jude says the Lord will do the rebuking; we do not need to rail against others – Jude 1:9
“An eye for an eye” in the scriptures is saying let the punishment fit the crime, to prevent unbalanced retaliation
