Pitched in Zalmonah, &c.— Zalmonah and Punon are not mentioned in chap. Numbers 21:4 where it is said, that they journeyed from Hor—to compass the land of Edom; but we are not told where they pitched, which is here supplied. Zalmonah was, probably, so called from the brazen serpent which was there erected: it signifies an image.
