Final answer:
The Lord set ambushments against the children of Ammon, Moab, and mount Seir in different biblical accounts as a form of divine punishment or judgment.
Step-by-step explanation:
The Lord set ambushments against the children of Ammon, Moab, and mount Seir in various instances as described in the Bible. One example can be found in the book of 2 Chronicles 20, where King Jehoshaphat and the people of Judah were faced with a vast army. The Lord caused confusion among the enemy forces, and they turned against each other, resulting in their own destruction. This intervention by the Lord is seen as a form of divine punishment or judgment.
