Numbers 20:18-21

18And Edom said to him, Thou shalt not pass by me, lest I come out against thee with the sword. 19And the children of Israel said to him, We will go by the highway: and if I and my cattle drink of thy water, then I will pay for it: I will only, without doing any thing else, go through on my feet. 20And he said, Thou shalt not go through. And Edom came out against him with many people, and with a strong hand. 21Thus Edom refused to give Israel passage through his border: therefore Israel turned away from him.
