When it was almost time for the Jewish Passover, Jesus went up to Jerusalem. 14In the temple courts he found people selling cattle, sheep and doves, and others sitting at tables exchanging money. 15So he made a whip out of cords, and drove all from the temple courts, both sheep and cattle; he scattered the coins of the money changers and overturned their tables. 16To those who sold doves he said, “Get these out of here! Stop turning my Father’s house into a market!” 17His disciples remembered that it is written: “Zeal for your house will consume me.” 18The Jews then responded to him, “What sign can you show us to prove your authority to do all this?” 19Jesus answered them, “Destroy this temple, and I will raise it again in three days.” 20They replied, “It has taken forty-six years to build this temple, and you are going to raise it in three days?” 21But the temple he had spoken of was his body. 22After 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.
It is perhaps understandable that the Jews were a little perplexed when Jesus told them he would raise the temple in three days because he was actually talking about his body as the temple after he was raised from the dead.
