Numbers 20:18

15 that our fathers go down to Egypt, and we dwell in Egypt many days, and the Egyptians do evil to us and to our fathers;

16 and we cry unto Jehovah, and He heareth our voice, and sendeth a messenger, and is bringing us out of Egypt; and lo, we [are] in Kadesh, a city [in] the extremity of thy border.

17 Let us pass over, we pray thee, through thy land; we pass not over through a field, or through a vineyard, nor do we drink waters of a well; the way of the king we go, we turn not aside -- right or left -- till that we pass over thy border.`

18 And Edom saith unto him, `Thou dost not pass over through me, lest with sword I come out to meet thee.`

19 And the sons of Israel say unto him, `In the highway we go, and if of thy waters we drink -- I and my cattle -- then I have given their price; only (it is nothing) on my feet I pass over.`

20 And he saith, `Thou dost not pass over;` and Edom cometh out to meet him with much people, and with a strong hand;

21 and Edom refuseth to suffer Israel to pass over through his border, and Israel turneth aside from off him.
