Mark 8:15 Meaning and Commentary

Mark 8:15

And he charged them
When they were in the ship, and had just recollected themselves, that they had took no care to bring any provisions with them:

saying, take heed, beware of the leaven of the Pharisees; and of the
leaven of Herod:
in Matthew, instead of "the leaven of Herod", it is read, "the leaven of the Sadducees": which are either the same, Herod and his courtiers being Sadducees, or favourers of them; or the Sadducees being sticklers for Herod, and his government, which the Pharisees had no good opinion of; or else distinct from one another; and so Christ cautions against the doctrines of the Pharisees, which regarded the traditions of the elders, and of the Sadducees, concerning the resurrection, and of the Herodians, who thought Herod to be the Messiah; and against the unreasonable request and demand of them all to have a sign from heaven, in proof of his own Messiahship; (See Gill on Matthew 16:6).

Mark 8:15 In-Context

14 Now they had forgotten to take bread, nor had they more than a single loaf with them in the boat;

15 and when He admonished them, "See to it, be on your guard against the yeast of the Pharisees and the yeast of Herod,"

16 they explained His words to one another by saying, "We have no bread!"

17 He perceived what they were saying, and He said to them, "What is this discussion of yours about having no bread? Do you not yet see and understand? Are your minds so dull of comprehension?
