Numbers 21:2-3

a And Israel vowed a vow to the  Lord and said, “If you will indeed give this people into my hand, then I will devote their cities to destruction.”
That is, set apart ( devote) as an offering to the Lord (for destruction); also verse 3
And the  Lord heeded the voice of Israel and gave over the Canaanites, and they devoted them and their cities to destruction. So the name of the place was called c Hormah.
 Hormah means destruction
