“After his resurrection,

They came out

Of the tombs.

They entered

The holy city.

They appeared

To many people.”

 

καὶ ἐξελθόντες ἐκ τῶν μνημείων μετὰ τὴν ἔγερσιν αὐτοῦ εἰσῆλθον εἰς τὴν ἁγίαν πόλιν καὶ ἐνεφανίσθησαν πολλοῖς.

 

Once again, this is unique to Matthew, since the other 3 gospels do not mention any appearance of holy dead people in Jerusalem.  Matthew clearly said that after the resurrection of Jesus (μετὰ τὴν ἔγερσιν αὐτοῦ), these holy righteous ones came out of their tombs (καὶ ἐξελθόντες ἐκ τῶν μνημείων).  They entered the holy city (εἰσῆλθον εἰς τὴν ἁγίαν πόλιν) of Jerusalem, where they appeared to many people (καὶ ἐνεφανίσθησαν πολλοῖς).  Thus, the general resurrection of the dead at the end times had already occurred.
