Isaiah 29:13

Wherefore the Lord said... — We pass from the effect to the cause. The blind stupor was the outcome of a long hypocrisy. Lip-homage and an estranged heart had been the notes of the religious life of Israel, and they could bear no other fruit.

Their fear toward me... — The words point to what we may call an anticipated Pharisaism. Side by side with the great commandments of the Law and with the incisive teaching of the prophets there was growing up even then a traditional system of ethics and religion, based upon wrong principles, ending in a dishonest casuistry and a formal devotion. Commentaries even then were darkening counsel by words without knowledge, as they did in the Mishna and the Gemara of the later days of Judaism (Matthew 15:3; Mark 7:6).
