"If a brother or sister sins, go and point out the fault, just between the two of you. If they listen to you, you have won them over." (NIV)

If your brother wrongs you, go and show him his fault, between you and him privately. If he listens to you, you have won back your brother. (AMP)

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. (KJV)
