Comentario citado sobre Isaías 48:9

וברוח אפיך AND WITH THE BREATH OF THY NOSTRILS — the breath that issues from both nostrils. Scripture speaks — if this were at all possible (i. e. if one may be permitted to speak so of God) of the Shechina (God) in the same manner as it does of a human monarch, in order to make peoples’ ears hear the facts in accordance with what usually happens to that they may understand the matter: when a man is angry the breath issues from his nostrils (and Scripture attributes this to God, also, when He is in anger). A similar idea is: (Psalms 18:9) “Smoke rose up in His nostril”, and also, (Job. 4:9) “By the breath of his nostril they are consumed”. And this is the meaning of what He said, (Isaiah 48:9) “For My name’s sake אאריך I will make long My אף”: when one’s anger subsides his breathing becomes long, whilst when one is in anger his breathing is short (consequently אאריך אפי signifies “I will not be angry”). The text continues ותהלתי אחטם לך which means “for the sake of My praise I will place a nose-ring in My nose to close up the nostrils against the anger and the breath so that they should not issue forth”. The word לך, for thee, in this text, means “for thy sake”, אחטם has the same meaning and root as in “a wild camel with a nose-ring (חֹטֶם)” which occurs in Mishna Treatise Sabbath (Mishnah Shabbat 5:1). Thus does the explanation appear to me. And wherever אף and חרון (i. e. where אף and words formed from the same root as חרון) occur in the Scriptures I say that it has the following sense: In the phrase חרה אף the first word is the same as (Job 30:30) “My bone is חרה with heat”, where חרה denotes burning and glowing, and this metaphor is used because the nostrils become hot and burning in a time of anger. The noun חרון is a derivation of חרה, just as רצון is a derivation of רצה, and therefore signifies “burning”. In the same way, חַמה which also signifies wrath really denotes heat (from a root יחם, not חמם, since the מ of חַמָה has no Dagesh. חַמָה is formed from יחם as עֵדָה, congregation, from יעד). That is why Scripture says, (Esther 1:12) וחמתו בערה בו “his wrath burned in him”, and when one’s wrath subsides one says, “his mind has become cooled” (נתקררה from קר cold).

משפחות הקהתי, “the families of the Kehatites.” The Torah deliberately did not write “the family (sing) of Kehat,” being aware that many of them would be members of the rebellion of Korach against Moses and Aaron. In spite of this foreknowledge, G’d said that every care must be taken not to cause the Kehatites to become guilty of serious sins. By writing the word אל תכריתו in this form the Torah added two letters (יו) of the name of G’d in order to append them to the name קהת. You may understand the idea behind this by means of a parable. A king had a son who kept bad company and eventually was arrested with the thieves he had joined. The king’s response was that at this time he would deal leniently with the thieves themselves seeing that his own son was also part of that group. However, he warned that there would not be a second time when such leniency would be practiced. This is also the meaning of Isaiah 48,9: “for the sake of My name I control My wrath; to My own glory I am patient with you and will not destroy you.”
