# Yet Peter rose up

"Rose up" means "began to act." Whether Peter was sitting or standing when he decided to act is not important. Alternate translation: "Yet Peter started out"

# stooping

Peter had to bend over in order to see inside the tomb because the entrance was very low. Alternate translation: "bending himself at the waist"

# the linen cloths by themselves

"only the linen cloths." This refers to the cloths that had been wrapped around Jesus's body when he was buried. Jesus was not there.
