Mark 2:2

And many were gathered together, so that there was no longer room for them, no, not even about the door: and he spake the word unto them.

The evidence of eye-witness reporting surfaces in this, as at many other places in this gospel. If Mark, as thought by many, was writing the things he had frequently heard the apostle Peter teach, or if, as a young man, he had been present and actually had seen some of the things related it would explain the brilliant eye-witness references in this gospel.

And he spake the word unto them ... The priority of importance which must be assigned to the "word" of the gospel is evident here as it was in Mark 1:38. Wonderful as were the miracles of Jesus, it was the life-giving word of God, and the delivery of it to mankind, which constituted the real purpose of his ministry.
