Be angry, and sin not: let not the sun go down upon your wrath:
All Commentaries on Ephesians 4:26 Go To Ephesians 4
Lucius Caecilius Firmianus Lactantius
AD 320
In time. God has enjoined us not to let the sun go down upon our wrath.
For if His anger had been altogether immortal, there would be no place after a fault for satisfaction or kind feeling, though He Himself commands men to be reconciled before the setting of the sun.
