Also, look! two men were conversing with him, who were Moses and Elijah. These appeared with glory and began talking about his departure [Greek, exodos] that he was destined to fulfill at Jerusalem.

Here, before the apostles’ eyes, was evidence that Jesus’ presence in Kingdom power would be a glorious heavenly one. Also, the conversation of the visionary Moses and Elijah about Jesus’ exodus was proof that his humiliating death was not something to avoid, as Peter had desired. In this tableau, Moses, who was used by God to give the Law to Israel, represented that Law covenant. Elijah represented the other prophets. Both the Law and the prophets had foretold Christ, his life, his suffering, his sacrifice, his glory. All pointed to Christ.
