Matt 13:13 For this reason I speak to them in parables, because seeing they do not see, and hearing they do not hear nor do they understand. 14 “And in them the prophecy of Isaiah is being fulfilled, which says, ‘You will keep on hearing but will never understand; you will keep looking, but will never see. 15 For the heart of this people has become dull, their ears can barely hear, and they have shut their eyes. Otherwise they might see with their eyes, hear with their ears, and understand with their hearts.
Matt 15:7 Hypocrites! Rightly did Isaiah prophesy about you, saying, 8 ‘This people honors Me with their lips, but their heart is far from Me. 9 And in vain they worship Me, teaching as doctrines the commandments of men.’”
Mark 4:11 And He told them, “To you has been given the secret of the kingdom of God. But for those who are outside, everything is in parables, so that 12 ‘Seeing, they may see and not perceive, and hearing, they may hear and not understand, so they may not turn back and be forgiven.’
Mark 7:6 And He said to them, “Rightly did Isaiah prophesy about you hypocrites, as it is written, ‘This people honors Me with their lips but their heart is far from Me. 7 And in vain they worship Me, teaching as doctrines the commandments of men.’
and the rest say the same thing. it's just repeating isaiah.
i did not use Matt 13:11
