Gill's Exposition of the Entire BibleIs it lawful for us to give tribute unto Caesar, or no? The Syriac and Persic versions here, as in the other evangelists, render it, "head money". The phrase, "for us", is here added, and on it lies the emphasis, and stress of the question; for the doubt pretended, was not whether it was lawful for the Romans to pay tribute to Caesar, but whether it was lawful for them who were Jews, were Abraham's seed, and, as they boasted, were never in bondage, but were the Lord's free people, to pay tribute to an Heathen emperor, or no.

Matthew Henry's Concise Commentary20:20-26 Those who are most crafty in their designs against Christ and his gospel, cannot hide them. He did not give a direct answer, but reproved them for offering to impose upon him; and they could not fasten upon any thing wherewith to stir up either the governor or the people against him. The wisdom which is from above, will direct all who teach the way of God truly, to avoid the snares laid for them by wicked men; and will teach our duty to God, to our rulers, and to all men, so clearly, that opposers will have no evil to say of us. |
