Numbers 20:18-21

18But Edom said to him, “You may not pass through me—or I will march out against you with the sword.”

19Bnei-Yisrael then said to him, “We will travel on the main road, and if we or our livestock even drink any of your water, we will pay its price. It’s nothing, just to pass through on foot!”

20He answered, “You may not pass through!” Yet Edom came out to oppose them with a large and well-armed people.

21Since Edom refused to permit Israel to cross through her territory, Israel turned away from them.
