Charles Ellicott Commentary Mark 2:8

"And straightway Jesus, perceiving in his spirit that they so reasoned within themselves, saith unto them, Why reason ye these things in your hearts?" — Mark 2:8 (ASV)

When Jesus perceived in his spirit.—The special mention of the spirit as the region of our Lord’s consciousness is, as part of this narrative, peculiar to St. Mark, and is not without importance in its bearing on the reality and completeness of our Lord’s human nature.
