24 Then Jesus said to His disciples, “If anyone wishes to come after Me, let him deny himself, and take up his cross and follow Me.
25 For whoever wishes to save his life will lose it; but whoever loses his life for My sake will find it.
26 For what will it profit a man if he gains the whole world and forfeits his soul? Or what will a man give in exchange for his soul?
27 For the Son of Man is going to come in the glory of His Father with His angels, and will then repay each one according to his deeds.
28 “Truly I say to you, there are some of those who are standing here who will not taste death until they see the Son of Man coming in His kingdom.”
1 And six days later Jesus *brought with Him Peter and James and John his brother, and *led them up on a high mountain by themselves.
2 And He was transfigured before them; and His face shone like the sun, and His garments became as white as light.
3 And behold, Moses and Elijah appeared to them, talking with Him.
4 And Peter answered and said to Jesus, “Lord, it is good for us to be here; if You wish, I will make three booths here, one for You, and one for Moses, and one for Elijah.”
5 While he was still speaking, behold, a bright cloud overshadowed them, and behold, a voice out of the cloud said, “This is My beloved Son, with whom I am well-pleased; listen to Him!”
6 And when the disciples heard this, they fell on their faces and were terrified.
7 And Jesus came to them and touched them and said, “Get up, and do not be afraid.”
8 And lifting up their eyes, they saw no one except Jesus Himself alone.
9 And as they were coming down from the mountain, Jesus commanded them, saying, “Tell the vision to no one until the Son of Man has risen from the dead.”
10 And His disciples asked Him, saying, “Why then do the scribes say that Elijah must come first?”
11 And He answered and said, “Elijah is coming and will restore all things;
12 but I say to you that Elijah already came, and they did not recognize him, but did to him whatever they wished. So also the Son of Man is going to suffer at their hands.”
13 Then the disciples understood that He had spoken to them about John the Baptist.

1 And Jesus was saying to them, “Truly I say to you, there are some of those who are standing here who will not taste death until they see the kingdom of God having come in power.”
2 And six days later, Jesus *took with Him Peter and James and John, and *brought them up on a high mountain alone by themselves. And He was transfigured before them;
3 and His garments were shining intensely white, as no launderer on earth can whiten them.
4 And Elijah appeared to them along with Moses and they were conversing with Jesus.
5 And Peter answered and *said to Jesus, “Rabbi, it is good for us to be here; let us make three booths, one for You, and one for Moses, and one for Elijah.”
6 For he did not know what to answer; for they became terrified.
7 Then a cloud formed, overshadowing them, and a voice came out of the cloud, “This is My beloved Son, listen to Him!”
8 And all at once when they looked around, they saw no one with them anymore, except Jesus alone.
9 And as they were coming down from the mountain, He gave them orders not to recount to anyone what they had seen, until the Son of Man rose from the dead.
10 And they seized upon that statement, arguing with one another what rising from the dead meant.
11 And they began asking Him, saying, “Why is it that the scribes say that Elijah must come first?”
12 And He said to them, “Elijah does first come and restore all things. And yet how is it written of the Son of Man that He will suffer many things and be treated with contempt?
13 But I say to you that Elijah has indeed come, and they did to him whatever they wished, just as it is written of him.”

27 But I say to you truthfully, there are some of those standing here who will not taste death until they see the kingdom of God.”
28 Now it happened some eight days after these words, that taking along Peter and John and James, He went up on the mountain to pray.
29 And it happened that while He was praying, the appearance of His face became different, and His clothing became white and gleaming.
30 And behold, two men were talking with Him, and they were Moses and Elijah,
31 who, appearing in glory, were speaking of His departure which He was about to fulfill at Jerusalem.
32 Now Peter and his companions had been overcome with sleep, but when they were fully awake, they saw His glory and the two men standing with Him.
33 And it happened that as they were leaving Him, Peter said to Jesus, “Master, it is good for us to be here; let us make three booths: one for You, and one for Moses, and one for Elijah”—not realizing what he was saying.
34 While he was saying this, a cloud formed and began to overshadow them; and they were afraid as they entered the cloud.
35 Then a voice came out of the cloud, saying, “This is My Son, My Chosen One; listen to Him!”
36 And when the voice had spoken, Jesus was found alone. And they kept silent, and reported to no one in those days any of the things which they had seen.

”For we did not make known to you the power and coming of our Lord Jesus Christ, following cleverly devised myths, but being eyewitnesses of His majesty. For when He received honor and glory from God the Father, such an utterance as this was made to Him by the Majestic Glory, “This is My beloved Son with whom I am well-pleased”— and we ourselves heard this utterance made from heaven when we were with Him on the holy mountain. And we have as more sure the prophetic word, to which you do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star arises in your hearts. Know this first of all, that no prophecy of Scripture comes by one’s own interpretation. For no prophecy was ever made by the will of man, but men being moved by the Holy Spirit spoke from God.“ ‭‭2 Peter‬ ‭1‬:‭16‬-‭21‬ ‭LSB‬‬ https://bible.com/bible/3345/2pe.1.18-21.LSB
