John Chrysostom, on 1Cor 14:19

“But in the church I had rather speak five words with my understanding, that I may instruct others also; than ten thousand words in a tongue.”

“"Howbeit in the Church I had rather speak five words with my understanding, that I might instruct others also." What is that, "speak with my understanding, that I might instruct others also?" "Understanding what I say," and "words which I can both interpret to others, and speak intelligently, and teach the hearers. Than ten thousand words in a tongue." Wherefore? "That I may instruct others," saith he. For the one hath but display only; the other, great utility: this being what he everywhere seeks, I mean the common profit. And yet the gift of tongues was strange, but that of prophecy familiar and ancient and heretofore given to many; this on the contrary then first given: howbeit it was not much cared for by him. Wherefore neither did he employ it; not because he had it not, but because he always sought the more profitable things: being as he was free from all vain-glory, and considering one thing only, how he might render the hearers better.”
