Matthew 18:27-30

18:27 The lord had compassion on that slave and released him, and forgave him the debt. 18:28 After he went out, that same slave found one of his fellow slaves who owed him one hundred silver coins. So he grabbed him by the throat and started to choke him, saying, ‘Pay back what you owe me!’ 18:29 Then his fellow slave threw himself down and begged him, ‘Be patient with me, and I will repay you.’ 18:30 But he refused. Instead, he went out and threw him in prison until he repaid the debt.

Matthew 18:35

18:35 So also my heavenly Father will do to you, if each of you does not forgive your brother from your heart.”
