Matthew 17:24-27 teaching about taxes (Tribute)

What I found interesting was Jesus' indirect confirmation of his kingship lineage back to David. And his being the Son of the King of kings, for the support of whose worship and service that money was collected.

Note John Gill's commentary.

Mat 17:24    And when they were come to Capernaum, they that received tribute money came to Peter, and said, Doth not your master pay tribute?

Mat 17:25    He saith, Yes. And when he was come into the house, Jesus prevented him, saying, What thinkest thou, Simon? of whom do the kings of the earth take custom or tribute? of their own children, or of strangers?

Mat 17:26    Peter saith unto him, Of strangers. Jesus saith unto him, Then are the children free.

Mat 17:27    Notwithstanding, lest we should offend them, go thou to the sea, and cast an hook, and take up the fish that first cometh up; and when thou hast opened his mouth, thou shalt find a piece of money: that take, and give unto them for me and thee.i

and said, doth not your master pay tribute? or the "didrachms", the half "shekel" money. Had this been the Roman tribute, the reason of such a question might have been either to have ensnared him, and to have known whether he was of the same mind with Judas, of Galilee, that refused to pay tribute to Caesar; or because they could not tell whether he was reckoned as an inhabitant, or citizen of that city; for, according to the Jewish canons (p), a man must be twelve months in a place, before he is liable to tribute and taxes; or because they might suspect him to be exempted, as a doctor, or teacher for the Jewish doctors, wise men, and scholars, were freed from all tribute and taxes (q) even from the "head money", the Syriac version here mentions; and which was a civil tax paid to kings (r); to which sense that version seems to incline: the rule concerning wise men or scholars, is this (s).

"They do not collect of them for the building a wall, or setting up gates, or for the hire of watchmen, and such like things; nor for the king's treasury; nor do they oblige them to give tribute, whether it is fixed upon citizens, or whether it is fixed on every man.''

But this was not the Roman tax, nor tribute, on any civil account, but the half shekel for religious service: and it may seem strange that such a question should be asked; and especially since it is a rule with them (t), that

"all are bound to give the half shekel, priests, Levites, and Israelites; and the strangers, or proselytes, and servants, that are made free; but not women, nor servants, nor children; though if they gave, they received it of them.''

.....

Jesus saith unto him, then are the children free; from paying custom, tribute, and taxes, and leaves Peter to make the application; and which he suggested might be made, either thus: supposing it was a civil tax, that since he was the son of David, king of Israel, was of his house and family, and heir apparent to his throne and kingdom; according to this rule, he must be exempt from such tribute: or, thus; taking it to have respect to the half shekel, paid on a religious account, for the service of the temple worship; that since he was the Son of the King of kings, for the support of whose worship and service that money was collected; and was also the Lord and proprietor of the temple, and greater than that, he might well be excused the payment of it.
