Matthew 18:14
“Even so it is not the will of your Father which is in heaven, that one of these little ones should perish.”
How think ye? if a man have an hundred sheep, and one of them be gone astray, doth he not leave the ninety and nine, and goeth into the mountains, and seeketh that which is gone astray?
And if so be that he find it, verily I say unto you, he rejoiceth more of that sheep, than of the ninety and nine which went not astray.
Even so it is not the will of your Father which is in heaven, that one of these little ones should perish.
Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.
But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established.
