“And when they were come to Capernaum, they that received tribute money came to Peter, and said, Doth not your master pay tribute?”
Matthew 17:24 — Greek Interlinear
Church Fathers on Matthew 17:24
The disciples were exceeding sorrowful when they heard of the Lord’s passion, and therefore that none might ascribe His suffering to compulsion, and not to a voluntary submission, he adds an incident which instances Christ’s power, and His submission; 'And when they were come to Capernaum, there came to Peter those who received the didrachma, and said unto him, Doth not your Master pay the didrachma?'
The Lord is called upon to pay the didrachma, (that is, two denarii,) for this the Law had enjoined upon all Israel for the redemption of their body and soul, and the use of those that served in the temple.
For when God slew the firstborn of Egypt, He then accepted the tribe of Levi for them. [margin note: Numb 3:44] But because the numbers of this tribe were less than the number of firstborn among the Jews, it was ordained that redemption money should be paid for the number that came short; and thence sprang the custom of paying this tax.
