Joshua 15:3

And it went out to the south side to Maalehacrabbim, and passed along to Zin, and ascended up on the south side unto Kadeshbarnea, and passed along to Hezron, and went up to Adar, and fetched a compass to Karkaa:

Ver. 3. To Maalehacrabbim,] i.e., To the ascent of scorpions, or of the mountains that were crooked as scorpions, or that abounded with scorpions. Jdg 1:36

Passed along to Zin.] A city whence that wilderness, not the same with that of Sin or Sinai, had its name.

To Hezron, and went up to Adar.] These two places are Num 34:4 called Hazaraddar.
