Fiery Enthusiasm Burns Away Imperfections

Rav Menachem Mendel of Rimanov zy”a (Sefer Ilna D’Chaya) writes that the “kohen” in this pasuk can be understood as a reference to Hashem, who is called a kohen (Sanhedrin 39A). The daughter of the kohen in the verse is a reference to Klal Yisroel. The pasuk is saying that when a Jewish soul strays from the proper path, he is desecrating his Father by dirtying his soul. The solution for this is to “burn it in fire”, meaning to purify himself through fiery avodas Hashem. When one serves Hashem with burning passion, he can burn away his sins and make his neshama pure again.
