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.
