Charles Spurgeon Commentary John 20:5

"and stooping and looking in, he seeth the linen cloths lying; yet entered he not in." — John 20:5 (ASV)

And he stooping down, and looking in, saw the linen clothes lying;

So that he knew that they had not taken away the body of Jesus; for, if they had, they certainly would not have taken off the linen clothes. It would have been very difficult, and would have taken considerable time to unwrap the cold grave-clothes when they were bound to the body by the unguents that had been used: He saw the linen clothes lying;

Yet went he not in.

Perhaps, out of reverence; or, possibly, out of deference to the older man, he would give him the preference, and let him enter first.
