“Geliloth.” This is called “Gilgal” in Joshua 15:7.
“in front of the ascent of Adummim.” Geliloth/Gilgal is “in front of” the ascent of Adummim. The meaning of the Hebrew is not clear, and thus “in front of” can here mean to the east of or to the south of Gilgal. The location of this Gilgal is uncertain. This could be a different Gilgal than the one where Israel had its camp near Jericho.
“Bohan the son of Reuben.” See Joshua 15:6.
