Matthew 15:16

"Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up?"

"Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?"

"But they understood not that saying, and were afraid to ask him."

"And he called the multitude, and said unto them, Hear, and understand:"

"But they understood not this saying, and it was hid from them, that they perceived it not: and they feared to ask him of that saying."

"How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?"

"And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken."

"For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat."
