Judges 10:7-9

7 And the anger of the LORD was hot against Israel, and he sold them into the hands of the Philistines, and into the hands of the children of Ammon.

8 And that year they vexed and oppressed the children of Israel: eighteen years, all the children of Israel that were on the other side Jordan in the land of the Amorites, which is in Gilead.

9 Moreover the children of Ammon passed over Jordan to fight also against Judah, and against Benjamin, and against the house of Ephraim; so that Israel was sore distressed.
