Matthew 27:52

And the graves were opened - By the earthquake; and many bodies of saints which slept, i.e. were dead, sleep being a common expression for death in the Scriptures.

And the graves were opened - "Graves" or sepulchres were most commonly made, among the Jews, in solid rocks or in caves of rocks. The rending of the rocks, therefore, would lay them open. The graves were opened by this earthquake, but the dead in them did not rise until after his resurrection.

And many bodies of the saints arose - Of course, it is not known who these were, nor what became of them. It is probable that they were persons who had recently died, and they appear to have been known in Jerusalem; at least, had the ancient saints risen, they would not have been known, and would not so soon have been credited as those who had recently died.

Which slept - Which had died. The death of saints is often called "sleep," Daniel 12:2; 1 Corinthians 15:18; 1 Thessalonians 4:15.

27:52 Some of the tombs were shattered and laid open by the earthquake, and while they continued unclosed (and they must have stood open all the Sabbath, seeing the law would not allow any attempt to close them) many bodies of holy men were raised, (perhaps Simeon, Zacharias, John the Baptist, and others who had believed in Christ, and were known to many in Jerusalem,) And coming out of the tombs after his resurrection, went into the holy city (Jerusalem) and appeared to many - Who had probably known them before: God hereby signifying, that Christ had conquered death, and would raise all his saints in due season.
