Numbers 21:2-4

Amplified Bible

² So Israel made a vow to the Lord, and said, “If You will indeed hand over these people to me, then I will utterly destroy their cities.” ³ The Lord heard the voice of Israel and handed over the Canaanites; then they utterly destroyed them and their cities. So the name of the place was called Hormah (dedicate to destruction).

⁴ Then they set out from Mount Hor by the way of the [branch of the] Red Sea [called the Gulf of Aqabah], to go around the land of Edom; and the people became impatient, because [of the challenges] of the journey.
