“And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.”
King James Version (KJV)
15:7 After much debate - It does not appear that this was among the apostles themselves. But if it had, if they themselves had debated at first, yet might their final decision be from an unerring direction. For how really soever they were inspired, we need not suppose their inspiration was always so instantaneous and express, as to supersede any deliberation in their own minds, or any consultation with each other. Peter rose up - This is the last time he is mentioned in the Acts.
Ac 15:7 When there had been much disputing. One side insisted that the Gentiles must keep the law of Moses, the other that they were not under the Mosaic covenant at all. Peter rose. Probably silent until this time. He arose to rehearse his own experiences which had given him new light. A good while ago. Nine or ten years before. For the account of Peter's conversion of the Gentiles, see Ac 10:9-48 11:4-18.
