John Gill Bible Commentary

Peter saith unto him,.... The Vulgate Latin reads, "and he said": and so the Ethiopic, and Munster's Hebrew Gospel; but without doubt Peter is meant, and rightly expressed; whose answer to Christ's question is, of strangers: meaning not foreigners, or such who formerly belonged to other nations, but were now taken captive, and brought into subjection; but their own native subjects, so called, in distinction from their domestics, their children, and those of their own family: 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.
