John 2:18-25

So the Jews replied to him, “What sign will you show us for doing these things?” Jesus answered, “Destroy this temple, and I will raise it up in three days.” Therefore the Jews said, “This temple took forty-six years to build, and will you raise it up in three days?” But he was speaking about the temple of his body. So when he was raised from the dead, his disciples remembered that he had said this, and they believed the Scripture and the statement Jesus had made. While he was in Jerusalem during the Passover Festival, many believed in his name when they saw the signs he was doing. Jesus, however, would not entrust himself to them, since he knew them all and because he did not need anyone to testify about man; for he himself knew what was in man.
