John 2:18-25

So the Jews answered and said to Him, “What sign do You show to us, since You do these things?” Jesus answered and said to them, “Destroy this temple, and in three days I will raise it up.” Then the Jews said, “It has taken forty-six years to build this temple, and will You raise it up in three days?” But He was speaking of the temple of His body. Therefore, when He had risen from the dead, His disciples remembered that He had said this to them; and they believed the Scripture and the word which Jesus had said. Now when He was in Jerusalem at the Passover, during the feast, many believed in His name when they saw the signs which He did. But Jesus did not commit Himself to them, because He knew all men, and had no need that anyone should testify of man, for He knew what was in man.
