What does Matthew 17:25 mean?
Jesus and the disciples have arrived in Capernaum, Jesus' place of official residence (Matthew 4:13). Peter has been approached by some collectors of the temple tax. This was not a Roman tax. Jewish men, 20 years and older, were required by the law of Moses to contribute two drachmas, or half a shekel, to the temple once a year (Exodus 30:13–16). These collectors have asked Peter if his teacher Jesus plans to pay the tax. That might have been a rhetorical question, which really meant "your master needs to pay the tax."Peter now replies that Jesus plans to pay the tax. Peter then enters the house where Jesus is, perhaps to ask Jesus for the money or where to get the money. Before Peter can speak, though, Jesus begins to ask Peter about it. Did Peter answer yes too quickly, assuming Jesus would pay the tax when He did not plan to do so?
Jesus calls Peter by his original name, Simon, and asks about a specific issue: Do kings collect taxes from their own children, or from others? Peter will give the obvious answer to the question. Kings do not collect taxes from their own sons. Jesus concludes His point in the following verse.
