John 2:18-22The Message (MSG)
18-19 But the Jews were upset. They asked, “What credentials can you present to justify this?” Jesus answered, “Tear down this Temple and in three days I’ll put it back together.”
20-22 They were indignant: “It took forty-six years to build this Temple, and you’re going to rebuild it in three days?” But Jesus was talking about his body as the Temple. Later, after he was raised from the dead, his disciples remembered he had said this. They then put two and two together and believed both what was written in Scripture and what Jesus had said.
