1 Corinthians 14:4

He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.

He who speaks in another language edifies himself, but he who prophesies edifies the assembly.

He that speaketh in a tongue edifieth himself; but he that prophesieth edifieth the church.

he who is speaking in an `unknown' tongue, himself doth edify, and he who is prophesying, an assembly doth edify;

The one who speaks in a tongue edifies himself, but the one who prophesies edifies the church.
