Mark 8:13-15

¹³And leaving them, he went up again into the ship, and passed to the other side of the water.

¹⁴And they forgot to take bread; and they had but one loaf with them in the ship.

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