Matthew 16:5

"And when His disciples," so it is said, "were come to the other side, they forgot to take bread. Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees." And why said He not plainly, Beware of their teaching? His will is to remind them of what had been done, for He knew they had forgotten. But for accusing them at once there seemed to be no reasonable ground, but to take the occasion from themselves, and so to reprove them, would make the charge admissible. "And why did He not then reprove them, when they said, 'Whence should we have so many loaves in the wilderness?' for it seemed a good time then to say what He says here." That He might not seem to rush hastily on the miracle. And besides, He would not blame them before the multitude, nor seek honor in their presence. And now too the accusation had greater reason, for that after repetition of the miracle they were so minded.

How had they no bread, seeing that as soon as they had filled seven baskets they entered into the boat, and came into the parts of Magedan? There they hear that they ought to take heed of the leaven of the Pharisees and Sadducees. But the Scripture is witness that they had forgotten to take the baskets with them.

They were bound to their Master with so great affection, that they were unwilling to part from Him for even a moment of time. And herein it should be observed how far they were from any longing for delicacies, when they took so small care for necessaries, that they had even forgotten to take bread, without which human weakness cannot support itself. He said unto them, Take heed and beware of the leaven of the Pharisees; and of the Sadducees.

(non occ.) As the Lord had left the Pharisees on account of their unbelief, so now He teaches His disciples to be on their guard against their doctrine; whence it follows, And when His disciples were come to the other side, they had forgotten to take bread.
