Mark 8:14 YLT

¹²  and having sighed deeply in his spirit, he saith, 'Why doth this generation seek after a sign? Verily I say to you, no sign shall be given to this generation.'

¹³  And having left them, having entered again into the boat, he went away to the other side;

¹⁴  and they forgot to take loaves, and except one loaf they had nothing with them in the boat,

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.'
