Catch
.“They sent certain of the Pharisees … . to catch Him in His words.”—Mark xii. Here the Greek word is αγρενω, to take by hunting. They were to lie upon the catch till they found occasion against Him.
Youʹll catch it. Youʹll get severely punished. Here “it” stands for the indefinite punishment, such as a whipping, a scolding, or other unpleasant consequence.
