{Then therefore} (	ote oun). After Peter in time and
influenced by the boldness of Peter. {And he saw and believed}
(kai eiden kai episteusen). Both aorist active indicative
(second and first). Peter saw more after he entered than John did
in his first glance, but John saw into the meaning of it all
better than Peter. Peter had more sight, John more insight. John
was the first to believe that Jesus was risen from the tomb even
before he saw him. According to  Lu 24:12  Peter went away
"wondering" still. The Sinaitic Syriac and 69 and 124 wrongly
read here "they believed." John was evidently proud to be able to
record this great moment when he believed without seeing in
contrast to Thomas ( 20:29 ). Peter and John did not see the
angels.
