Mark 12:14-15

And when they were come, they say unto him, Teacher, we know that thou art true, and carest not for any one; for thou regardest not the person of men, but of a truth teachest the way of God: Is it lawful to give tribute unto Cæsar, or not? 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.
