It was common in those days for the entrance to a tomb to be about 3 feet high (note that these verses say people “bent down” to look into the tomb). With no windows, it was probably dark and hard to see inside the tomb clearly without crawling inside. What did Peter and John see when they crawled into the tomb (v. 6-8)? What do you think they were thinking? What do you think John “believed” (v. 8, especially given the parenthetical statement in v. 9)?
