John 2:18-22

The Jews then responded to him, “What sign can you show us to prove your authority to do all this?” Jesus answered them, “Destroy this temple, and I will raise it again in three days.” They replied, “It has taken forty-six years to build this temple, and you are going to raise it in three days?” But the temple he had spoken of was his body. After he was raised from the dead, his disciples recalled what he had said. Then they believed the scripture and the words that Jesus had spoken.
