1 Corinthians 14:4 Meaning and Commentary

1 Corinthians 14:4

He that speaketh its an unknown tongue
Be it the Hebrew language, or any other; some copies, and the Ethiopic version, read, "with tongues":

edifieth himself;
his heart may be warmed, his affections raised, his devotion kept up, and he be in a very spiritual and comfortable frame, knowing and understanding what he himself says:

but he that prophesieth, edifieth the church:
which is the great end of the Gospel ministry, which is for the edifying the body of the church: wherefore that which tends to the edification of more, even the whole church, must be preferable to that, which at most can only edify one, and that the speaker himself.

1 Corinthians 14:4 In-Context

2 for he who is speaking in an [unknown] tongue -- to men he doth not speak, but to God, for no one doth hearken, and in spirit he doth speak secrets;
3 and he who is prophesying to men doth speak edification, and exhortation, and comfort;
4 he who is speaking in an [unknown] tongue, himself doth edify, and he who is prophesying, an assembly doth edify;
5 and I wish you all to speak with tongues, and more that ye may prophecy, for greater is he who is prophesying than he who is speaking with tongues, except one may interpret, that the assembly may receive edification.
6 And now, brethren, if I may come unto you speaking tongues, what shall I profit you, except I shall speak to you either in revelation, or in knowledge, or in prophesying, or in teaching?
