Numbers 21:20-22

²⁰And from Bamoth to the valley in the open country of Moab, and to the top of Pisgah looking over Jeshimon.

²¹And Israel sent men to Sihon, king of the Amorites, saying,

²²Let me go through your land: we will not go into field or vine-garden, or take the water of the springs; we will go by the highway till we have gone past the limits of your land.
