Matthew 16:14

11 how do ye not understand that I did not speak to you of bread -- to take heed of the leaven of the Pharisees and Sadducees?`

13 And Jesus, having come to the parts of Cesarea Philippi, was asking his disciples, saying, `Who do men say me to be -- the Son of Man?`

15 He saith to them, `And ye -- who do ye say me to be?`

16 and Simon Peter answering said, `Thou art the Christ, the Son of the living God.`

17 And Jesus answering said to him, `Happy art thou, Simon Bar-Jona, because flesh and blood did not reveal [it] to thee, but my Father who is in the heavens.
