Doesn’t it make sense to go back and look at what Jesus had previously stated about those who will not see death until they see the ‘Son of man coming in his kingdom’?
Matthew 16:28 Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
It wasn’t long after the last statement that this happened…
Matthew 17:1-9 And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart, And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light. And, behold, there appeared unto them Moses and Elias talking with him. Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias. While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him. And when the disciples heard it, they fell on their face, and were sore afraid. And Jesus came and touched them, and said, Arise, and be not afraid. And when they had lifted up their eyes, they saw no man, save Jesus only. And as they came down from the mountain, Jesus charged them, saying, Tell the vision to no man, until the Son of man be risen again from the dead.
It has nothing to do with Moses and Elijah except for the fact that the apostles present got to witness a little bit of the Lord of Glory. I think that is awesome. Good old, “jump to the gun”, Peter wanted to make tents for them all, but God Almighty spoke up and said? "This is my beloved Son, in whom I am well pleased; hear ye him".
I have a good priest, no?
