ציטירנדיקער פּירוש אויף ישעיהו 41:3

THY RAIMENT WAXED NOT OLD UPON THEE. “The clouds of [Divine] Glory brushed their garments and pressed them so that they looked like freshly ironed articles; and so it was with their children, as they grew their garments grew with them.” This is Rashi’s language and also are the words of Agadah.⁷²Shir Hashirim Rabbah 4:23. But Rabbi Abraham ibn Ezra wrote: “Other scholars say that they took many garments out [of Egypt]. And it is possible that it was not in the nature of the manna to produce perspiration [thus enabling their garments to last so long]. And so also he stated that neither did thy feet swell, meaning that He gave them strength or that He led them slowly.” But his [Ibn Ezra’s] words are not correct, for Moses mentions this to them in order to say that upon observing the commandment [of G-d] they will have food and raiment, and renew [their] strength, even as they lived by the manna forty years and they had garments, and the way with their feet they treadeth not.⁷³Isaiah 41:3. All of this was miraculous, for by every thing that proceedeth out of the mouth of the Eternal doth man live⁶⁷Verse 3 before us. and becomes supported. And if you were to cover a rafter with a new cloth it would wear out in forty years even though there is no perspiration, how much less man, that is a worm.⁷⁴Job 25:6.

וירדף עד דן, “he pursued as far as Dan.” This is a reference to the מדת הדין, “the attribute of Justice.” Once the attribute of Justice caught up with these kings there was no need for Avram to pursue any further. We find a similar expression in Isaiah 41,3 ירדפם יעבור שלום, “He pursues them, he goes unharmed.”

AND HE DIVIDED HIMSELF, BY NIGHT. Rashi wrote: “In accordance with the plain sense of the verse it means [that they divided into groups] as is the manner of those who pursue their enemies when they flee in different directions. By night means that even after it became dark, they did not cease pursuing them.”
The correct interpretation is that he pursued the enemies to Dan during the daytime with his entire army. When it became dark and he was not able to see by which road they fled, he divided his people and servants into two or three groups, taking one part with him, and they pursued them on all roads, smiting them as far as Hobah, which is on the left hand of Damascus. Then he returned from pursuing them. The order of the words [in the verse are thus interpreted as follows]: “And he divided himself, he and his servants, by night.”
