John Gill Commentary Mark 12:15

"Shall we give, or shall we not give? But he, knowing their hypocrisy, said unto them, Why make ye trial of me? bring me a denarius, that I may see it." — Mark 12:15 (ASV)

expressed in their flattering titles and characters of him, and which lay hid in their secret designs against him; which being thoroughly known to him,

said to them, why tempt you me: bring me a penny, that I may see
it ;
what it is, that is required for tribute; (See Gill on Matthew 22:18), (See Gill on Matthew 22:19).
