¹At that time, the disciples came to Jesus and said, “Who, then, is the greatest in the kingdom of the heavens?” ²Then Jesus called a child to himself and placed him at the focus of their attention, ³and he said, “Truly, I say to you, unless you change your ways and become like children, you certainly will not enter into the kingdom of the heavens. ⁴So it is whoever humbles himself like this child who is the greatest in the kingdom of the heavens, ⁵and whoever receives one such child in my name receives me. ⁶But whoever causes offence to one of these little ones who believe in me – it would be more profitable for him for an ass-driven millstone to be hung around his neck and for him to be drowned in the wide open sea. ⁷Woe to the world because of its snares! For it is necessary that snares come, but woe to that man through whom the snare comes. ⁸But if your hand or your foot ensnares you, cut it off and throw it away. For it is better for you to enter into life lame or maimed than to have two hands or two feet and be thrown into the age-abiding fire. ⁹And if your eye ensnares you, pluck it out and throw it away. It is better to enter into life with one eye than to have two eyes and to be thrown into fiery Gehenna. ¹⁰See that you don't despise one of these little ones. For I say to you that their angels in the heavens continuously see the face of my father in the heavens. ¹¹For the son of man came to save that which was lost. ¹²What do you think? If a certain man has one hundred sheep, and one of them goes astray, will he not leave the ninety-nine and go into the mountains and seek the one which is going astray? ¹³And if it should happen that he finds it, truly, I say to you that he rejoices over it more than over the ninety-nine which did not go astray. ¹⁴In this way it is not the will of your father in the heavens that one of these little ones should be lost. ¹⁵But if your brother sins against you, go and remonstrate with him as a matter between you and him alone. If he heeds you, you have won your brother over. ¹⁶But if he does not heed you, take one or two people with you in order that by the attestation of two or three witnesses, every matter may be established. ¹⁷And if he refuses to heed them, tell the assembly. And if he refuses to heed the assembly, let him be to you like the Gentile and the tax collector. ¹⁸Truly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loosen on earth will be loosened in heaven. ¹⁹Again, truly, I say to you that if two of you agree on earth about any matter which they ask about, it will be done for them by my father in the heavens. ²⁰For where two or three are gathered in my name, there I am in their midst.” ²¹Then Peter came to him and said, “Lord, how many times should I forgive my brother if he sins against me? Up to seven times?” ²²Jesus said to him, “I do not say to you up to seven times, but up to seventy times, seven times over. ²³This is why the kingdom of the heavens is like a man who was a king, who wished to settle accounts with his servants. ²⁴As he started to settle them, a certain debtor of ten thousand talents was brought to him. ²⁵But as he did not have the means to repay, his master ordered him to be sold, with his wife and children and everything he had, and for repayment to be made. ²⁶So the servant fell down and prostrated himself before him, and he said, ‘My lord, have patience with me, and I will repay you everything.’ ²⁷At this, that servant's master had compassion on him, and he released him and cancelled his debt. ²⁸But when that servant went out, he found one of his fellow servants, who owed him one hundred denaries, and when he had seized him, he choked him and said, ‘Repay me what you owe.’ ²⁹So his fellow servant fell down at his feet and pleaded with him and said, ‘Be patient with me, and I will repay you.’ ³⁰But he refused and instead went away, and he had him thrown him in prison until he should pay what was owed. ³¹But when his fellow servants saw what had happened, they were very grieved, and they went and explained to their master everything that had happened. ³²Then his master called for him and said to him, ‘You wicked servant, I cancelled all that debt for you, since you appealed to me. ³³Should not you too have shown your fellow servant mercy, as I for my part showed you mercy?’ ³⁴And his master became angry and delivered him to the torturers until he should repay everything owed to him. ³⁵In this manner my upper-heavenly father will also deal with you, if you do not all forgive your brother his trespasses from your hearts.”
