“et quomodo nos audivimus unusquisque linguam nostram in qua nati sumus ?”
“And how hear we every man in our own tongue, wherein we were born?”
“How is it then that each of us hears them in his own native language?”
“How do we hear, everyone in our own native language?”
“And how hear we, every man in our own language wherein we were born?”
Without literature, or good education, they being worse thought of on that account than the ordinary sort of that nation were; besides, they thought no prophet was to be expected from Galilee, Joh 1:46.
2. They acknowledge that they spoke intelligibly and readily their own language (which they were the most competent judges of), so correctly and fluently that none of their own countrymen could speak it better: We hear every man in our own tongue wherein we were born (v. 8), that is, we hear one or other of them speak our native language. The Parthians hear one of them speak their language, the Medes hear another of them speak theirs; and so of the rest; v. 11, We do hear them speak in our tongues the wonderful works of God. Their respective languages were not only unknown at Jerusalem, but probably despised and undervalued, and therefore it was not only a surprise, but a pleasing surprise, to them to hear the language of their own country spoken, as it naturally is to those that are strangers in a strange land. (1.) The things they heard the apostles discourse of were the wonderful works of God, megaleia tou Theou—Magnalia Dei, the great things of God. It is probable that the apostles spoke of Christ, and redemption by him, and the grace of the gospel; and these are indeed the great things of God, which will be for ever marvellous in our eyes. (2.) They heard them both praise God for these great things and instruct the people concerning these things, in their own tongue, according as they perceived the language of their hearers, or those that enquired of them, to be. Now though, perhaps, by dwelling some time at Jerusalem, they were got to be so much masters of the Jewish language that they could have understood the meaning of the disciples if they had spoken that language, yet, [1.] This was more strange, and helped to convince their judgment, that this doctrine was of God; for tongues were for a sign to those that believed not, 1 Cor 14 22. [2.] It was more kind, and helped to engage their affections, as it was a plain indication of the favour intended to the Gentiles, and that the knowledge and worship of God should no longer be confined to the Jews, but the partition-wall should be broken down; and this is to us a plain intimation of the mind and will of God, that the sacred records of God's wonderful works should be preserved by all nations in their own tongue; that the scriptures should be read, and public worship performed, in the vulgar languages of the nations.
Verses 5-13 The difference in languages which arose at Babel, has much hindered the spread of knowledge and religion. The instruments whom the Lord first employed in spreading the Christian religion, could have made no progress without this gift, which proved that their authority was from God.
