Commentators note that this verse, listing towns like Bilhah and Ezem, is part of a genealogical and geographical record for the tribe of Simeon. Interestingly, many of these same locations are also listed in Joshua 15 as belonging to the tribe of Judah. This highlights the close relationship between the two tribes, with Simeon's inheritance being situated within the territory of Judah. The exact sites of some of these ancient towns are now unknown.
