Expositor's Bible Commentary Commentary Mark 16:5

"And entering into the tomb, they saw a young man sitting on the right side, arrayed in a white robe; and they were amazed." — Mark 16:5 (ASV)

Mark makes no attempt to explain how the stone was removed. Once inside the tomb the women saw a young man dressed in a white robe; his dress suggests an angel (cf. Matthew 28:2). No human eyes saw the resurrection, but angels, as witnesses of God’s actions, could report what happened. The reaction of the women to the angel was what one would expect: “They were alarmed.”
