Sirach 27:30-28:7

Revised Standard Version Catholic Edition

³⁰ Anger and wrath, these also are abominations,
    and the sinful man will possess them.
28 He that takes vengeance will suffer vengeance from the Lord,
    and he will firmly establish^[a] his sins.
² Forgive your neighbor the wrong he has done,
    and then your sins will be pardoned when you pray.
³ Does a man harbor anger against another,
    and yet seek for healing from the Lord?
⁴ Does he have no mercy toward a man like himself,
    and yet pray for his own sins?
⁵ If he himself, being flesh, maintains wrath,
    who will make expiation for his sins?
⁶ Remember the end of your life, and cease from enmity,
    remember destruction and death, and be true to the commandments.
⁷ Remember the commandments, and do not be angry with your neighbor;
    remember the covenant of the Most High, and overlook ignorance.
