Arcana Coelestia # 2685
2685. 'Withdrawing herself about a bowshot' means the extent to which the state was away from the doctrine of truth. This is clear from the meaning of 'being withdrawn from' as being away from, and from the meaning of 'a bow' as the doctrine of truth, dealt with in the next paragraph. 'Shot' means that it was as far away as possible, as far away as an arrow could be shot from a bow. Here the expression 'a bowshot' is used because the bow is used in reference to the spiritual man, who is also called 'an archer', as he is in verse 20 - 'and he dwelt in the wilderness, and was an archer'.
Numbers 21:14-16

the slope of the valleys that incline toward the dwelling of Ar, leans on the border of Moab."

From there they traveled to Beer: that is the well of which Yahweh said to Moses, "Gather the people together, and I will give them water."
