ציטירנדיקער פּירוש אויף ישעיהו 29:15

דגל מחנה דן צפונה, “the flag of the camp of Dan, to the North.” It is a well known fact that two golden calves were erected by Jerobam in the territory of Dan [an historical inaccuracy as it hosted only one of these golden calves based on Shir Hashirim 2,4]. Jerobam erected one of these golden calves in Bet El (Kings I 12,29), whereas he placed the second one in the territory of Dan. It was quite appropriate to be in the North as material wealth is perceived as originating from the North and Dan caused the whole world to become darkened by the sin of idolatry. We have a Scriptural verse alluding to this in Isaiah 29,15 “Who do their work in the dark and say: ‘who sees us,’ etc.” Although the sun rises in the East, it is at its brightest when it is in the South at midday. The sun, by traveling westwards before it sets, also illuminates the West with its light. The only direction which the sun does not illuminate directly is the North. This is why the North is associated with the concept of darkness. The expression צפון השמש, “hidden from the sun,” is a double entendre as the word צפון also means “North.” In light of historical developments it was therefore quite appropriate that the camp of Dan should be situated to the North of the Tabernacle. In view of the problems the tribe of Dan would create for the Jewish people as a whole, this camp was in need of atonement, i.e. that G’d’s light should shine upon it notwithstanding the shortcomings mentioned which darkened the halo of that camp. This is why we find that Micah 7, 8 exclaims: “though I have fallen, I rise again; though I sit in darkness, the Lord is my light.” The tribe of Dan was joined by the tribes of Asher and Naftali who helped to brighten the darkness as we know from Deut. 33,24 and 23 describing Asher having plentiful oil, oil being the raw material from which man-made light is derived. The Torah also describes Naftali as blessed by the Lord and well satisfied (same passage), indicating that it did not suffer from spiritual darkness. This camp journeyed last. The Torah here used the expression לאחרונה where we would have expected it to write simply ואחרונה יסעו, without the introductory preposition ל. The letter ל points at the letter ה at the end of that word which itself is a reminder of the last letter ה in the tetragram, the symbol of the aspect of the attribute of Justice even in the name Hashem. The three tribes Dan, Asher, Naftali, are all understood as part of the term “the camp of Dan.” It parallels the camp of Uriel in the celestial spheres, the latter being flanked by the angels Daniel and Tamael on the left side of the Shechinah. In the celestial spheres that camp is known as the camp of Uriel, a camp which David hinted at in connection with the atonement achieved by the sacrificial offerings. When he said in Psalm 118,27: ‘The Lord is G’d, He has given us light, bind the festival offerings to the horns of the altar, etc.,” he addressed that attribute represented by Uriel.

and...with hypocrites who go into hidden places to do their deeds in the dark.

והקריב אותו לאשם. It has already been explained in 7,1 as well as in my commentary on Leviticus 1,2 that the guilt offering, אשם in the main applies to inadvertent sins committed involving misuse of sacred matters, or misuse of the sacred domain of the Temple, such as unauthorised persons entering it, or ritually unclean persons entering it, etc. Just as in the case of the sin offering, חטאת, if that sin had been committed deliberately it would have resulted in the karet penalty, and if not atoned for through teshuvah would have resulted in the guilty person’s eternally being cut off from the collective soul of the Jewish people.
Our sages in Erchin 15 and 16 have already stated that the principal sins for which a person is afflicted with the נגע צרעת, are bad-mouthing people and haughtiness, both of which are perceived by the sages as direct trespass against G’d’s Holiness. Even though badmouthing is generally perpetrated in secret not affording the victim a chance to defend himself against the accusation and character assassination, the prophet Isaiah 29,15 views it as the perpetrators saying “who sees us, who takes note of us?” In other words, the prophet considers the “secrecy” as worse than the sin itself, as it suggests that G’d is unable to see it, and therefore represents a gross insult directed at G’d.
Concerning arrogant, haughty behaviour. We read in Psalms 101,5 “He who slanders his friend in secret I will destroy; I cannot endure the haughty and proud man.” G’d is portrayed as if the sinner is “trying to steal part of G’d’s “clothing.” G’d declares that such people cannot co-exist with Him in the same universe. (Sotah 5).
We have evidence in our scriptures (Chronicles II 26, 16-19) that King Uzziah’s arrogance was punished with tzoraat for his haughtiness, as this sin was considered a trespass against G’d Himself.
