A.T. Robertson Commentary John 20:6

"Simon Peter therefore also cometh, following him, and entered into the tomb; and he beholdeth the linen cloths lying," — John 20:6 (ASV)

Entered and beholdeth (εισηλθεν κα θεωρε). Aorist active and present active indicative. Peter impulsively went on in and beholds (θεωρε, vivid term again, but of careful notice, θεωρεω, not a mere glance βλεπω such as John gave in verse 5).
