“Hee saith, Yes. And when hee was come into the house, Iesus preuented him, saying, What thinkest thou, Simon? of whom doe the kings of the earth take custome or tribute? of their owne children, or of strangers?”
1611 King James Version (KJV)
17:25 Jesus prevented him - Just when St. Peter was going to ask him for it. Of their own sons, or of strangers? - That is, such as are not of their own family.
Mt 17:25 He saith, Yes. Peter, as usual, answered before he reflected, and then came to Jesus with the matter. Jesus prevented him. Peter came into the house to speak about it, but Christ knew his thoughts and spoke first. Of whom do the kings of the earth take custom? Not of their own children, but from subjects. Hence, Christ, the King's Son, for whom the temple was built, was not subject to tax for the benefit of the temple. The Son of the King would not pay tribute to the King. For the origin of this temple tax, see Ex 30:12 2Ch 24:5.
