Hebrews 5:11

"For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them."

"As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction."

"For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them."

"I have yet many things to say unto you, but ye cannot bear them now."

"And this he said to prove him: for he himself knew what he would do."

"And he cometh to Bethsaida; and they bring a blind man unto him, and besought him to touch him."

"Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken:"

"Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed."

"And when the queen of Sheba heard of the fame of Solomon concerning the name of the LORD, she came to prove him with hard questions."
