“And he called the multitude, and said unto them, Hear, and understand:”
Matthew 15:10 — Greek Interlinear
Church Fathers on Matthew 15:10
The Lord had shewn that the Pharisees were not worthy to accuse those who transgressed the commands of the elders, seeing they overthrew the law of God themselves; and He again proves this by the testimony of the Prophet; 'Hypocrites, well did Esaias prophesy of you, saying, This people honoureth me with their lips, but their heart is far frost me.'
Hypocrite signifies dissembler, one who feigns one thing in his outward act, and bears another thing in his heart. These then are well called hypocrites because under cover of God’s honour they sought to heap up for themselves earthly gain.
Esaias saw before the hypocrisy of the Jews, that they would craftily oppose the Gospel, and therefore he said in the person of the Lord, 'This people honoureth me with their lips, &c.'
