Albert Barnes Commentary Matthew 28:6

"He is not here; for he is risen, even as he said. Come, see the place where the Lord lay." — Matthew 28:6 (ASV)

He is risen, as he said. He had often predicted that he would rise, but the disciples did not understand it, and consequently did not expect it (Matthew 16:21; Matthew 20:19).

The place where the Lord lay. The place where a body was deposited in a sepulchre was commonly a niche cut in the wall of the sepulchre.

The sepulchre was usually large; that of David was more than a hundred feet in length, cut out of solid rock underground, and separated into various apartments. All around the sides of those apartments were niches for the dead; or they were ranged around the sides, in places cut in the solid rock just large enough to contain the body. In such a place our Lord lay.
