But if thine heart turn away,.... From the true God, and the right worship of him, and from his commands, statutes, and judgments: so that thou wilt not hear; the voice of the Lord and obey it, or hearken to his laws, and do them: but shalt be drawn away; by an evil heart, and by the ill examples of others: and worship other gods and serve them; the gods of the Gentiles, the idols of the people, besides the one living and true God, the God of Israel.
