And after six days had passed, Jesus took Peter, James and John aside alone and went up to a high mountain [i.e., probably Mt. Tabor, which was nearby]. [There] His whole appearance was [miraculously] changed in front of them.

And it happened about eight days after Jesus said these things that He took Peter, John and James with Him and went up in the mountain to pray. [Note: This was probably Mt. Tabor, which was nearby].
