Judg 2:12

“After the death of Joshua the son of Nave [Nun] they forsook the God of their fathers and served idols, Baalim and Ashtaroth; and the Lord in anger delivered them up to the hands of plunderers, and they continued to be plundered by them and to be sold to their adversaries, and [they] could not at all stand before their enemies. Wherever they went forth, his hand was upon them for evil, and they were greatly distressed. And after this God sets judges, the same as our censors, over them. But not even these did they continue steadfastly to obey. So soon as one of the judges died, they proceeded to transgress more than their fathers had done by going after the gods of others and serving and worshiping them. Therefore the Lord was angry. "Since, indeed," he says, "this nation has transgressed my covenant which I established with their fathers and has not hearkened to my voice, I will not remove from them any of the nations which Joshua left at his death." And thus, throughout almost all the annals of the judges and of the kings who succeeded them, while the strength of the surrounding nations was preserved, he meted wrath out to Israel by war and captivity and a foreign yoke, as often as they turned aside from him, especially to idolatry.”

“They followed strange gods. What is here said of the children of Israel, as to their falling so often into idolatry, is to be understood of a great part of them; but not so universally, as if the true worship of God was ever quite abolished among them: for the succession of the true church and religion was kept up all this time by the priest and Levites, at least in the house of God in Silo. (Challoner) — At different times God raised up deliverers, who were taken from among his people, and no doubt abhorred the impiety of the multitude.”
