Nahum
God is jealous, and the Lord avenges; The Lord avenges and is furious. The Lord will take vengeance on His adversaries, And He reserves wrath for His enemies;
The Lord is slow to anger and great in power, And will not at all acquit the wicked. The Lord has His way In the whirlwind and in the storm, And the clouds are the dust of His feet. (Nahum 1:2-3 NKJV)
I agree that the Lord will take vengeance on His enemies, but that doesn’t change the fact that He told us to forgive our enemies.
