Mark 8:17

¹⁵  And he charged them, saying, Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod.

¹⁶  And they reasoned among themselves, saying, It is because we have no bread.

¹⁷  And when Jesus knew it, he saith unto them, Why reason ye, because ye have no bread? perceive ye not yet, neither understand? have ye your heart yet hardened?

¹⁸  Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?

¹⁹  When I brake the five loaves among five thousand, how many baskets full of fragments took ye up? They say unto him, Twelve.
