Números 21:23

Mas Sehón no dejó pasar á Israel por su término: antes juntó Sehón todo su pueblo, y salió contra Israel en el desierto: y vino á Jahaz, y peleó contra Israel.

And Sihon would not suffer Israel to pass through his border: but Sihon gathered all his people together, and went out against Israel into the wilderness: and he came to Jahaz, and fought against Israel.
