Luke 9:28-31
28 About eight days after Jesus had said these things, he went up a mountain to pray. He took Peter, John and James with him. 29 While Jesus was praying, his face became different to look at. His clothes also became very white. They were shining brightly.
30 Then two men appeared and they were talking with Jesus. They were Moses and Elijah. 31 They were very bright to look at. They talked with Jesus about how he would soon die in Jerusalem. This was how God wanted him to leave this world.
9:30Moses was a leader of God's people. He died about 1,400 years before Jesus was born. We can read about him in the Book of Exodus.
