And Nebo, and Baalmeon, (their names being changed,)
&c.] For Nebo was the name of an idol, after which perhaps the city was called: Baalmeon signifies "Baal's habitation", and where it is highly probable was a temple of his; and the children of Reuben, not liking to retain such idolatrous names, gave them others, but what they were it is not said; and certain it is, that when these places came into the hands of the Moabites, their ancient names were restored to them, as appears from ( Isaiah 15:2 ) ( Jeremiah 48:23 )
and Shibmah;
the same with Shebam, ( Numbers 32:3 ) , and gave other names unto the cities which they built; but they are neither known, nor did they always continue, as has been observed.
