Numbers 33:41

And they removed from Mount Umano, and encamped in Zalmona, a place of thorns, and narrow (or squalid), in the land of the Edomaee; and there the soul of the people was distressed on account of the way;

AND THEY JOURNEYED FROM MOUNT HOR, AND PITCHED IN ZALMONAH. These places — Zalmonah and Punon — 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, and they [therefore] spoke against G-d, and Moses, 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 pole, 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. 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, 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., 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, [all these] being places in the valley of Zered.
