Leviticus 19:4 - Matthew Poole's English Annotations on the Holy Bible

Turn not your hearts and faces from me, whom alone you pretend to respect, unto them. He intimates, that their turning to idols is a turning from God, and that they could not serve both God and idols. Unto idols: the word signifies such as are no gods, or nothings, as they are called, 1 Corinthians 8:4, many idols having no being, but only in the fancy of their worshippers, and all of them having no virtue or power to do good or evil, Isaiah 41:23. Molten gods, nor graven gods neither, as appears from Exo 20, whereby we learn that such expressions are generally to be understood synecdochically.
