Well did Isaiah prophesy of you (kalw eprophteusen peri mwn Esaia). There is sarcasm in this pointed application of Isaiah's words ( Isaiah 29:13 ) to these rabbis. He "beautifully pictured" them. The portrait was to the very life, "teaching as their doctrines the commandments of men." They were indeed far from God if they imagined that God would be pleased with such gifts at the expense of duty to one's parents.
