Chasidut על מלאכי 2:6

And here the mitzvah of lightning the Menorah (Numbers 8:2) will be explained, that truly it is [done] in every human being and in every time through the kohen. We already mentioned that a person is called candle/light: the 248 members and inside them soul (Nefesh) and spirit (Ruach), behold, these are candle (NeR). Even though a person has also a Neshamah (essence) in any instance, through a sin, the Neshamah separates from the person, and only soul and spirit are left. And the Alshich has written that the kohen is hinted at by the text, "the lips of the kohen guard knowledge and they seek Torah from his mouth" (Malachi 2:7) "he held many back from iniquity" (Malachi 2:6); and so too is mentioned in the Zohar "whoever seizes the hand of an evildoer and enables him to leave the evil path, rises three levels, which does not happen to other human beings, etc (Zohar 2:128b:3); and it seems to me to recall what I heard as way of musar [on the verse] "seeks the good of his people" (Esther 10:3) - the one who speaks of ethics and admonishes at the gate how should a person cling to the Holy One of Blessing, and after that all those who listen will be connected in unity, so that the speaker would make the words of the Holy One cling to them, and this is "to seize the hand of the evildoer" to raise them. And these are wise words.
