The children of Israel again did that which was evil in the sight of Yahweh, and served the Baals, and the Ashtaroth, and the gods of Syria, and the gods of Sidon, and the gods of Moab, and the gods of the children of Ammon, and the gods of the Philistines; and they forsook Yahweh, and didn't serve him.
Notice how much more diversified Israel’s idolatry had become. The Israelites were now worshipping foreign gods as well as the gods of Canaan. Furthermore they abandoned the worship of Yahweh. This situation was a new low for them in Judges.
