SEV Biblia, Chapter 14:28
Y si no hubiere intrprete, calle en la Iglesia, y hable a sí mismo y a Dios.
Clarke's Bible Commentary - 1 Corinthians 14:28
Verse 28. But if there be no interpreter] If there be none present who can give the proper sense of this Hebrew reading and speaking, then let him keep silence, and not occupy the time of the Church, by speaking in a language which only himself can understand.
John Gill's Bible Commentary
Ver. 28. But if there be no interpreter , etc.] None that has the gift of interpretation of divers tongues, and he that speaks with them has not that, which was sometimes the case: let him keep silence in the church ; let him not make use of his gift publicly before the whole congregation, since without an interpreter it will be entirely useless: and let him speak to himself, and to God ; he may make use of his gift to his own edification, and to the glory of God, by speaking with a low voice, or in his heart, which he himself may be conscious of, and God the searcher of hearts, and that knows all languages, fully understands; and so may be edified himself, and God may be glorified by him; whereas, if he was to use it openly and publicly, it would not only be unprofitable, but an hinderance to others: or he might retire to his own house, and there exercise it by himself, and in the presence of God, when it might be of some use and advantage to himself, but would be highly improper to bring it into the church, or public congregation; for instead of assisting, it would but dampen their devotion, and therefore it was very reasonable he should be silent there.
Matthew Henry Commentary
Verses 26-33 - Religious exercises in public assemblies should have this view; Let all be done to edifying. As to the speaking in an unknown tongue, if another were present who could interpret, two miraculous gifts might be exercised at once, and thereby the church be edified, and the faith of the hearers confirmed at the same time. As to prophesying, two or thre only should speak at one meeting, and this one after the other, not all at once. The man who is inspired by the Spirit of God will observ order and decency in delivering his revelations. God never teaches me to neglect their duties, or to act in any way unbecoming their age of station.

Robertson's NT Word Studies
14:28 {But if there be no interpreter} (ean de me ei diermeneutes). Third class condition. Earliest known instance and possibly made by Paul from verb in verse #27. Reappears in Byzantine grammarians. {Keep silence in church} (sigatw en ekklesiai). Linear action (present active imperative). He is not even to speak in a tongue once. He can indulge his private ecstasy with God.
