1 Samuel 7:4

Then the children of Israel, heeding the earnest words of their great prophet and leader, did put away Baalim and Ashtaroth, they completely did away with the worship of strange gods, and served the Lord only, they restored His exclusive worship. Here again the fact is brought out that idolatry had been practiced, but in such a manner that the Jehovah worship had outwardly been kept up. It was the same mixture of true and false religion which is now found in so many parts of Christendom, where antichristian religious societies are existing in the very midst of so-called Christian congregations.
