JMNT(i)
3 Now the one habitually prophesying (or: normally publicly speaking [God's message] and sharing light ahead of time) is constantly speaking an act of building (a construction; an edification) – even a calling to the side to give relief, aid and comfort and encouragement (or: a speaking as, and doing the work of, a paraclete), as well as a speech of stimulation, soothing and gentle influence or incentive – to people (or: among humans; for mankind).
4 The person habitually speaking in a tongue (or: language) constantly upbuilds and edifies himself, yet the person constantly prophesying (publicly speaking [God's message] before others) continuously upbuilds, edifies and constructs the called-out community.
5 Now I continue intending (purposing; willing; wanting) all you folks to be habitually speaking in tongues (or: with languages), yet preferably that you would be constantly prophesying (or: should keep on speaking publicly before others [as God's spokesmen, proclaiming God's message]), for the one repeatedly prophesying [is] of greater [importance; influence] than the one habitually speaking in tongues (or: with languages) – outside of this exception: [that] he should continue on to interpret (or: translate), so that the called-out assembly can receive an upbuilding (or: may take hold of, and get, edification; would grasp [the] construction).
6 So now, brothers (= fellow believers), if I should come to you repeatedly speaking in language after language (or: continuously speaking in tongues), what will I be benefiting, augmenting or furthering you folks – unless instead I speak either on an unveiling (a revelation; a disclosure), or in intimate knowledge based upon my experience and insight, or with a prophecy (a proclamation [from God]), or by a teaching?
