Matthew 16:10-14

Nor the seven loaves of the four thousand, and how many large baskets you picked up?

How is it that you do not understand that I did not speak to you about bread? But beware of the leaven of the Pharisees and Sadducees.”

Then they understood that He did not say to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees. Peter’s Confession of Christ

Now when Jesus came into the region of Caesarea Philippi, He was asking His disciples, “Who do people say that the Son of Man is?”

And they said, “Some say John the Baptist; and others, Elijah; and still others, Jeremiah, or one of the other prophets.”
