What does the change of name of Zephath to Hormah confirm?
Judges 1:17 (ESV)
17And Judah went with Simeon his brother, and they defeated the Canaanites who inhabited Zephath and devoted it to destruction. So the name of the city was called Hormah.
As with Hebron and Debir earlier in the chapter, so here the shift in the name from Zephath to Hebron points up that Israel, by the hand of Lord, had displaced the Canaanites.
