Numbers 21:2-3

2 aAnd 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
3And 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 cHormah.
 Hormah means destruction
