Matthew 18:1–5
“At that time the disciples came to Jesus, saying, ‘Who is the greatest in the kingdom of heaven?’ And calling to him a child, he put him in the midst of them and said, ‘Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven. Whoever humbles himself like this child is the greatest in the kingdom of heaven. Whoever receives one such child in my name receives me.’” [46:54]

Matthew 18:10–14
“‘See that you do not despise one of these little ones. For I tell you that in heaven their angels always see the face of my Father who is in heaven. What do you think? If a man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go in search of the one that went astray? And if he finds it, truly, I say to you, he rejoices over it more than over the ninety-nine that never went astray. So it is not the will of my Father who is in heaven that one of these little ones should perish.’” [50:20]

Matthew 18:15–17
“‘If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.’” [55:46]
