Isaiah 29:13 - Matthew Poole's English Annotations on the Holy Bible

Draw near me, to wit, in acts of worship, with their mouth and with their lips; with outward devotions, and the profession of religion. But have removed their heart far from me; they do not pay me that love, and fear, and obedience which I require, and prefer before all sacrifices and external services. Their fear toward me is taught by the precept of men; they worship me not in such way and manner as I have commanded and prescribed, but according to their own and other men's inventions, preferring the devices and traditions of their false prophets before my institutions. For this was a common error among the Jews, as we learn from Jeremiah 7:31 Hosea 5:11, and many other scriptures; and thus our blessed Saviour expounds this very place, Matthew 15:7-9.
