Numbers 20:18-22

¹⁸And Edom said unto him, Thou shalt not pass through my land, lest I come against thee with the sword.

¹⁹And the children of Israel said unto him, We will go by the highway: and if we drink of thy water, I and my cattle, then will I pay its value; I will do thee no injury, only on foot will I pass through.

²⁰And he said, Thou shalt not pass through; and Edom came out against him with much people, and with a strong hand.

²¹And as Edom thus refused to permit Israel to pass through his border, Israel turned away from him.

²²And they set forward from Kadesh; and the children of Israel, the whole congregation, came unto mount Hor.
