9 So also you, unless e you utter by the tongue speech that is clear , how will it be known what is spoken ? For you will be speaking into the air . 10 There are, perhaps , a great many kinds of languages in the world , and no kind is without meaning . 11 If then I do not know the meaning of the language , I will be to the one who speaks a barbarian , and the one who speaks will be a barbarian to me. 12 So also you, since you are zealous of spiritual gifts, seek to abound for the edification of the church . 13 Therefore let one who speaks in a tongue pray that he may interpret .
Matthew Henry's Commentary on 1 Corinthians 14:9-13
Commentary on 1 Corinthians 14:6-14
(Read 1 Corinthians 14:6-14)
Even an apostle could not edify, unless he spoke so as to be understood by his hearers. To speak words that have no meaning to those who hear them, is but speaking into the air. That cannot answer the end of speaking, which has no meaning; in this case, speaker and hearers are barbarians to each other. All religious services should be so performed in Christian assemblies, that all may join in, and profit by them. Language plain and easy to be understood, is the most proper for public worship, and other religious exercises. Every true follower of Christ will rather desire to do good to others, than to get a name for learning or fine speaking.
