The answer is: Moses and Elijah

Mark 9:4

The event known as the Transfiguration is one of those spectacular moments in the Gospels that takes the reader behind the scenes of a heavenly revelation. In Mark 9:4, we catch a glimpse of both Moses and Elijah appearing alongside Jesus. These two figures could not be more significant; Moses represents the Law, garnering respect for guiding the Israelites out of Egypt and receiving the Ten Commandments (Exodus 20). Elijah, on the other hand, is a prominent prophet known for standing up against injustice and idolatry (1 Kings 18).

The very fact that they collaborate with Jesus bolsters his role in fulfilling these traditional aspects of faith. While Mark’s account is vivid, it's interesting to consider that both characters had notable departures from earth—Moses is said to have died and been buried mysteriously (Deuteronomy 34:5), while Elijah made a dramatic exit in a whirlwind, riding a chariot of fire (2 Kings 2:11). This meeting reinforces thematic continuities; Jesus appears to be the bridge connecting the old covenant and the new, appealing to the Jewish audience.

Additionally, did you know that in prophetic literature, Elijah is expected to return before the great day of the Lord? This echoes loudly with the ultra-specific confirmation of Jesus’ role. It provokes the intriguing thought on how witnessing such a mystical event might have inspired the three disciples—Peter, James, and John—creating a lasting imprint on their spiritual journeys! It's moments like these that propel their faith from observation to participation in something divine.
