Numbers 20:18-21

18And Edom said unto him, Thou shalt not pass through me, lest I come out with the sword against thee. 19And the children of Israel said unto him, We will go up by the highway; and if we drink of thy water, I and my cattle, then will I give the price thereof: let me only, without doing anything else, pass through on my feet. 20And he said, Thou shalt not pass through. And Edom came out against him with much people, and with a strong hand. 21Thus Edom refused to give Israel passage through his border: wherefore Israel turned away from him.
