John Wesley on Acts 2:4

And they began to speak with other tongues - The miracle was not in the ears of the hearers, (as some have unaccountably supposed,) but in the mouth of the speakers. And this family praising God together, with the tongues of all the world, was an earnest that the whole world should in due time praise God in their various tongues. As the Spirit gave them utterance - Moses, the type of the law, was of a slow tongue; but the Gospel speaks with a fiery and flaming one.
