Numbers 20:17-21

17Let us pass, I pray thee, through thy country; we will not pass through fields, or through vineyards, neither will we drink water out of the wells: we will go by the king's road; we will not turn to the right hand nor to the left, until we have passed thy border.

18But 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 high way; and if we drink of thy water, I and my cattle, then I will pay for it: I will only, without anything else, go through on my feet.

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

21Thus Edom refused to give Israel passage through his territory; and Israel turned away from him.
