Matthew 18:13-15 New King James Version (NKJV)

13. And if he should find it, assuredly, I say to you, he rejoices more over that sheep than over the ninety-nine that did not go astray.

14. Even so it is not the will of your Father who is in heaven that one of these little ones should perish.

15. “Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother.
