Comentario citado sobre Números 33:45

משם נסעו, “from there they journeyed onwards;” from the place called iyyey havavarim. The next place they encamped was called nachal zered. In Parshat Massey, that place is referred to as divon Gad (Numbers 33,45. According to some commentators the differences in the names of the encampments is due to their sometimes being referred to according to the brooks of water there, and in others according to the names thy had been known as. They are called here as their sources of water, seeing that was most important to them.

ויחנו בנחל זרד, “they encamped in the valley of the river Zered.” In Parshat Massey, however, we read that the Israelites first came to Divon Gad, but there only land locations are mentioned, whereas here rivers are mentioned also. The reason may be that the Torah was interested here to report what occurred at Beer.

AND THEY JOURNEYED FROM MOUNT HOR, AND PITCHED IN ZALMONAH. These places — Zalmonah and Punon¹⁵Verse 42 here. — were by the way of the Red Sea circling the land of Edom, and the soul of the people became impatient because of the way,¹⁶Above, 21:4. and they [therefore] spoke against G-d, and Moses¹⁷Ibid., Verse 5. on the way, and G-d sent against them the fiery serpents whilst they were travelling and when they rested in camp. Then Moses made the serpent of brass, which they carried upon a pole¹⁸Ibid., Verse 9. all the way, and [kept it] when they encamped in Zalmonah and Punon, and it was not removed from them until they pitched in Oboth.¹⁹Verse 43 here. Therefore Scripture there, in narrating this episode [of the fiery serpents, above in Chapter 21], did not mention the name of the place [from which they set forth again, i.e., Zalmonah and Punon] and [merely] stated, And the children of Israel journeyed, and pitched in Oboth,²⁰Above, 21:10. without saying “and they journeyed from such-and-such a place and pitched in Oboth,” as it does with all the [other stages of their] journeyings. This is because the matter [of the brass serpent] continued throughout this way — from the time that they journeyed from Mount Hor until they pitched in Oboth, and they journeyed from Oboth and pitched in Ije-abarim.²¹Ibid., Verse 11. — Verse 44 here. From there they journeyed and they pitched in Divon-gad, and then in Almon-diblathaim, and [finally] in the mountains of Abarim,²²Verses 45-47 here. [all these] being places in the valley of Zered.²³Above, 21:12.
