Albert Barnes Commentary Numbers 11:3

"And the name of that place was called Taberah, because the fire of Jehovah burnt among them." — Numbers 11:3 (ASV)

Taberah—that is, “burning”: it was not the name of a station (and accordingly is not found in the list given in Numbers 33) but the name of the spot where the fire broke out. This incident might seem to have occurred at the station called—from another, still more terrible event which shortly followed—Kibroth-hattaavah.
