Numbers 20:14-21

14 And Moses sent messengers from Kadesh to the king of Edom, Thus said your brother Israel, You know all the travail that has befallen us:

15 How our fathers went down into Egypt, and we have dwelled in Egypt a long time; and the Egyptians vexed us, and our fathers:

16 And when we cried to the LORD, he heard our voice, and sent an angel, and has brought us forth out of Egypt: and, behold, we are in Kadesh, a city in the uttermost of your border:

17 Let us pass, I pray you, through your country: we will not pass through the fields, or through the vineyards, neither will we drink of the water of the wells: we will go by the king's high way, we will not turn to the right hand nor to the left, until we have passed your borders.

18 And Edom said to him, You shall not pass by me, lest I come out against you with the sword.

19 And the children of Israel said to him, We will go by the high way: and if I and my cattle drink of your water, then I will pay for it: I will only, without doing anything else, go through on my feet.

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

21 Thus Edom refused to give Israel passage through his border: why Israel turned away from him.
