1Cor 14:18

“Further, because he had run down the possessors of this gift, as though they had no such great thing; that he might not seem to hold them cheap, as being himself destitute of it, see what he saith: "I thank God, speaking with tongues more than ye all." And this he doth also in another place intending, namely, to take away the advantages of Judaism and to show that henceforth they are nothing, he begins by declaring that himself had been endowed with them, yea, and that in very great excess; and then he calls them "loss," thus saying, "If any man thinketh to have confidence in the flesh, I more: circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as touching the law, a Pharisee; as touching zeal, persecuting the Church; as touching the righteousness which is the law, found blameless." And then, having signified himself to have the advantage of all, he saith, "Howbeit what things were gain to me, those have I counted loss for Christ." So also he doth here, saying, "I speak with tongues more than ye all." Do not ye therefore glory as though ye only had the gift. For I also possess it, yea more than ye.”

“I speak with tongues more than ye all - He understood more languages than any of them did: and this was indispensably necessary, as he was the apostle of the Gentiles in general, and had to preach to different provinces where different dialects, if not languages, were used. In the Hebrew, Syriac, Greek, and Latin, he was undoubtedly well skilled from his education; and how many he might understand by miraculous gift we cannot tell. But, even literally understood, it is very probable that he knew more languages than any man in the Church of Corinth.”
