Perhaps he was startled by this sight, and therefore drew back and let Peter enter the sepulchre first; but it is likewise very possible that the reason of his not mentioning the circumstance in his gospel was because humility made him anxious to conceal the fact of his having been more highly favoured than Peter.
The guards at this moment began to revive, and rising, gathered up their lances, and took down the lamps, which were on the door, from whence they cast a glimmering weak light on surrounding objects.
