'Descent' in the Bible

The men of Ai struck down about thirty-six of their men, and pursued them from the gate as far as Shebarim and struck them down on the descent, so the hearts of the people melted and became as water.

As they fled from before Israel, while they were at the descent of Beth-horon, the Lord threw large stones from heaven on them as far as Azekah, and they died; there were more who died from the hailstones than those whom the sons of Israel killed with the sword.
