{Looked round about} (periblepsamenos). Another picture
of the looks of Jesus and in Mark alone as in  3:5,34 . "To see
what impression the incident had made on the Twelve" (Bruce).
"When the man was gone the Lord's eye swept round the circle of
the Twelve, as he drew for them the lesson of the incident"
(Swete). {How hardly} (P(9373) duskol(9373)). So  Lu 18:24 .  Mt 19:23 
has it: "With difficulty (duskol(9373)) shall a rich man." See on
Matthew for this word.
