Philistines and Ammonites oppress Israel
Israel served the gods of every neighboring nation, and God sold them into the hands of the Philistines and Ammonites for 18 years.
They put away the foreign gods from among them and served Yahweh; and his soul was grieved for the misery of Israel.
Judges 10:16 (World English Bible)
This time, when Israel cried out, God answered that they should ask the gods they had chosen to save them. The people put away their foreign gods and served Yahweh, and Scripture says he could bear Israel's misery no longer.

18 years (Judges 10:8). Ussher overlaps some oppressions and rest periods, counting each rest from the previous deliverance, so that the judges fit the 480 years of 1 Kings 6:1.
