Numbers 22:2

The children of Israel traveled, and encamped in the plains of Moab beyond the Jordan at Jericho.

Moab was very afraid of the people, because they were many. Moab was distressed because of the children of Israel.

Moab said to the elders of Midian, “Now this multitude will lick up all that is around us, as the ox licks up the grass of the field.”
