Also, here is the prophecy Jesus made which did not pass, repeated among multiple NT books:
“For the Son of Man is going to come in the glory of His Father with His angels, and will then repay every man according to his deeds. 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.“ (Matthew 16: 27, 28)
“Behold, I have told you in advance. So if they say to you, ‘Behold, He is in the wilderness,’ do not go out, or, ‘Behold, He is in the inner rooms,’ do not believe them. For just as the lightning comes from the east and flashes even to the west, so will the coming of the Son of Man be. Wherever the corpse is, there the vultures will gather.
But immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from the sky, and the powers of the heavens will be shaken. And then the sign of the Son of Man will appear in the sky, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of the sky with power and great glory. And He will send forth His angels with a great trumpet and they will gather together His elect from the four winds, from one end of the sky to the other.
Now learn the parable from the fig tree: when its branch has already become tender and puts forth its leaves, you know that summer is near; so, you too, when you see all these things, recognize that He is near, right at the door. Truly I say to you, this generation will not pass away until all these things take place.“ (Matthew 24: 25-34)
“Then they will see the Son of Man coming in clouds with great power and glory. And then He will send forth the angels, and will gather together His elect from the four winds, from the farthest end of the earth to the farthest end of heaven. Now learn the parable from the fig tree: when its branch has already become tender and puts forth its leaves, you know that summer is near. Even so, you too, when you see these things happening, recognize that He is near, right at the door. Truly I say to you, this generation will not pass away until all these things take place…“ (Mark 13:26-30)
“Then they will see the Son of Man coming in a cloud with power and great glory. But when these things begin to take place, straighten up and lift up your heads, because your redemption is drawing near. Then He told them a parable: Behold the fig tree and all the trees; as soon as they put forth leaves, you see it and know for yourselves that summer is now near. So you also, when you see these things happening, recognize that the kingdom of God is near. Truly I say to you, this generation will not pass away until all things take place.“ (Luke 21:27-32)
