John Chrysostom — as excerpted in the Catena Aurea on Matthew 28:11-15

“(Hom. xc.) Of the signs which were shewn around Christ, some were common to the whole world, as the darkness; some peculiar to the watch, as the wonderful apparition of Angels, and the earthquake, which were wrought for the soldiers’ sake, that they might be stunned with amazement, and bear testimony to the truth. For when truth is proclaimed by its adversaries, it adds to its brightness. Which befel now; Some of the watch came into the city, and shewed unto the Chief Priests all the things that were done.”
