Matthew 18:23-35 (New King James Version)

23 Therefore the kingdom of heaven is like a certain king who wanted
to settle accounts with his servants. 24 And when he had begun to
settle accounts, one was brought to him who owed him ten thousand
talents. 25 But as he was not able to pay, his master commanded that
he be sold, with his wife and children and all that he had, and that
payment be made. 26 The servant therefore fell down before him,
saying, ‘Master, have patience with me, and I will pay you all.’ 27
Then the master of that servant was moved with compassion, released
him, and forgave him the debt.
28 “But that servant went out and found one of his fellow servants who
owed him a hundred denarii; and he laid hands on him and took him by
the throat, saying, ‘Pay me what you owe!’ 29 So his fellow servant
fell down at his feet[a] and begged him, saying, ‘Have patience with
me, and I will pay you all.’[b] 30 And he would not, but went and
threw him into prison till he should pay the debt. 31 So when his
fellow servants saw what had been done, they were very grieved, and
came and told their master all that had been done. 32 Then his master,
after he had called him, said to him, ‘You wicked servant! I forgave
you all that debt because you begged me. 33 Should you not also have
had compassion on your fellow servant, just as I had pity on you?’ 34
And his master was angry, and delivered him to the torturers until he
should pay all that was due to him.
35 “So My heavenly Father also will do to you if each of you, from his
heart, does not forgive his brother his trespasses.”
