Luke 24:16

And when she had thus said, she turned herself back, and saw Jesus standing, and knew not that it was Jesus.

But when the morning was now come, Jesus stood on the shore: but the disciples knew not that it was Jesus.

And their eyes were opened, and they knew him; and he vanished out of their sight.

After that he appeared in another form unto two of them, as they walked, and went into the country.
