1 Corinthians 14:30 - Matthew Poole's English Annotations on the Holy Bible

There were two modes or sorts of prophecies; the one ordinary, when the teacher came to those assemblies furnished with a revelation from some previous impression of God upon him, enabling him to give the sense of some scripture, or to open some Divine truth; not as we are, but by some influence of the Holy Spirit upon him, without the use of such means as we use. The other was, by some present afflatus or impression. The apostle seems not to speak of the latter; or if of both, he plainly lets them know, that even such a one was under the government of natural order, and obliged to do nothing confusedly and tumultuously, but might, without any offence to God, stay until the other had finished his discourse.
