Matthew Poole and continuators on Acts 2:4

4 And they were all filled with the holy Ghost , and began to speak with other tongues , as the spirit gave them utterance .

Those gifts and Graces which proceeded from him. The Apostles having them all in a more excellent manner than formerly, and the gift of Tongues superadded.

Than what were vernacular or natural to them.

[non-Latin text not transcribed], signifies more than barely to speak; implying they speak each Language in its perfection, after an Excellent, Eloquent and powerful manner; as from the holy Ghost whose works are perfect, non vox hominem sonat.
