Likutei Moharan 27:5/ליקוטי מוהר"ן כ״ז:ה׳

15. Now, when his voice is refined, then by making only his voice heard, <even> without speech, the Holy One saves him in his time of affliction. This is as in (Psalms 106:44), “He saw their affliction, when He heard their rinah”—by making his voice <heard> the Holy One sees whom it is that afflicts him.

2This is the meaning of (Deuteronomy 27:8), “a good baer (clarification).” <Rashi explains:> In seventy languages. <In other words, by means of the expositions of> the Torah, through which the voice is emitted, He gave us good in all <the seventy languages>. This is as in, B ’shamo Et Rinatam (“when He heard their song/supplication/outcry”), the first letters of which form the word BaER, and baer indicates explanation and exposition.
