John 2:18-25

18 The Jews then said to him, "What sign have you to show us for doing this?"
19 Jesus answered them, "Destroy this temple, and in three days I will raise it up."
20 The Jews then said, "It has taken forty-six years to build this temple, and will you raise it up in three days?"
21 But he spoke of the temple of his body.
22 When therefore he was raised from the dead, his disciples remembered that he had said this; and they believed the scripture and the word which Jesus had spoken.
23 Now when he was in Jerusalem at the Passover feast, many believed in his name when they saw the signs which he did;
24 but Jesus did not trust himself to them,
25 because he knew all men and needed no one to bear witness of man; for he himself knew what was in man.
