Charles Ellicott Commentary Matthew 11:4

"And Jesus answered and said unto them, Go and tell John the things which ye hear and see:" — Matthew 11:4 (ASV)

Go and show John again —There is no Greek adverb corresponding to the last word. St. Luke adds that in that same hour Jesus cured many of their infirmities and plagues, and of evil spirits (Luke 7:21), and they were therefore to carry back their report as eyewitnesses.
