Judges 10:7-9

7So the anger of the Lord was kindled against Israel, and He sold them into the hands of the Philistines and the Ammonites,

8and they oppressed and crushed Israel that year. For eighteen years they oppressed all the Israelites who were beyond the Jordan in the land of the Amorites, which is in Gilead.

9The Ammonites crossed the Jordan to fight against Judah, Benjamin, and the house of Ephraim, so that Israel was greatly distressed.
