Numbers 20:18-21

18But the Edomites answered, “You may not pass through our country. If you try, we’ll come out and attack you.”

19The Israelites replied, “We’ll stay on the main road, and if we or our livestock drink any of your water, we’ll pay for it. We want to pass through on foot. That’s all.”

20But the Edomites said, “You may not pass through.” Then they came out and attacked with many well-armed troops.

21Since the Edomites refused to let Israel go through their territory, the Israelites turned around and went a different way.
