Jesus prophesied His resurrection as a sign of His divinity

John 2:18-22

The Jews therefore answered him, “What sign do you show us, seeing that you do these things?” Jesus answered them, “Destroy this temple, and in three days I will raise it up.” The Jews therefore said, “It took forty-six years to build this temple! Will you raise it up in three days?” But he spoke of the temple of his body. When therefore he was raised from the dead, his disciples remembered that he said this, and they believed the Scripture, and the word which Jesus had said.
