Who did the women see at the tomb?
An angel Matthew 28:2 And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it. A young man Mark 16:5 And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted. Two men Luke 24:4 And it came to pass, as they were much perplexed thereabout, behold, two men stood by them in shining garments. Two angels John 20:12 And seeth two angels in white sitting, the one at the head, and the other at the feet, where the body of Jesus had lain.
