Ben Sira 28:5

5 If you cannot get rid of your anger, you have no hope of forgiveness - you are only a human being.

Ben Sira 28:5 In-Context

3 You cannot expect the Lord to pardon you while you are holding a grudge against someone else.
4 You yourself are a sinner, and if you won't forgive another person, you have no right to pray that the Lord will forgive your sins.
5 If you cannot get rid of your anger, you have no hope of forgiveness - you are only a human being.
6 Think about it! Some day you will die, and your body will decay. So give up hate and live by the Lord's commands,
7 the commands in the covenant of the Most High. Instead of getting upset over your neighbor's faults, overlook them.
