4 The one speaking in a lashon (tongue) edifies himself; but, the one speaking forth a dvar hanevu'ah (word of prophecy) edifies kehillah.
5 Now I desire all of you to speak in leshonot (tongues), and even more that you may speak forth a dvar hanevu'ah (word of prophecy) (BAMIDBAR 11:29). Now greater is the one speaking forth a dvar nevu'ah (word of prophecy) than the one speaking in leshonot, unless he gives the pitron (interpretation) of the leshonot (tongues), that the kehillah (congregation) may receive the edification.
6 But now, Achim b'Moshiach, if I come to you speaking in leshonot (tongues), what will I benefit you unless I speak to you either with a dvar hisgalus (a word of revelation) or with a dvar da'as or with a dvar nevu'ah or with a dvar hora'ah (word of teaching)?
7 So even lifeless things, like the flute or harp, if they do not articulate a distinction in the notes, how will it be known what is being played on the flute or on the harp?
8 Indeed, if a shofar gives an unclear trumpet call, who will prepare himself for krav (battle)? [BAMIDBAR 10:9; YIRMEYAH 4:19]
9 So also unless you by your lashon (tongue) render an intelligible dvar Torah, how will the thing being uttered be known? For you will be merely speaking into the air.
10 There are doubtless many kinds of foreign languages in the Olam Hazeh, and not one is meaningless.
