Jesus’ predictions of a first century Parousia ( παρουσι. α , presence of Christ)
Matt. 10:23 - "Truly I say to you, you will not finish going through the cities of Israel until the Son of Man comes."
Matt. 16:28 - "Truly I say to you, there are some who are standing here who will not taste death until they see the Son of Man coming in His kingdom. (not the transfiguration because no rewards were given then.)
Matt. 24:34 - "Truly I say to you, this generation will not pass away until all these things take place." (This covered the destruction of the temple and the return of Christ.)

Matt. 26:64 - "You [speaking to the high priest] will see the Son of Man coming on the clouds of heaven."
