Matthew Henry, Commentary on the Whole Bible… (1700s)
“ And rebuke; convince and reprove such as contradict or gainsay, or neglect and do not receive the truth as they should, or retain it in unrighteousness—those who hear it not with such a believing and obedient mind and heart as they ought, but, instead of this (it may be) live in contrary practices, showing themselves stubborn and disobedient, and to every good work reprobate. Rebuke with all authority, as coming in the name of God, and armed with his threatenings and discipline, whoever make light of which will do it at their peril. Ministers are reprovers in the gate. ”
