Mark 8:17 YLT

¹⁵  and he was charging them, saying, 'Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod,'

¹⁶  and they were reasoning with one another, saying -- 'Because we have no loaves.'

¹⁷  And Jesus having known, saith to them, 'Why do ye reason, because ye have no loaves? do ye not yet perceive, nor understand, yet have ye your heart hardened?

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

¹⁹  When the five loaves I did brake to the five thousand, how many hand-baskets full of broken pieces took ye up?' they say to him, 'Twelve.'
