They came to Capernaum, and the people who collected the double drachma tax for Temple maintenance approached Peter and said “Doesn’t your teacher pay the double drachma tax?”

Peter answered “Yes.”

When he went to the house, Jesus started talking about what had just happened before Peter had a chance to. “What do you think Simon Peter? Do earthly kings collect taxes from their sons or from strangers?”

“From strangers” he answered.

“Then the sons owe nothing. But so we won’t annoy them, do this. Go cast your fishing line into the sea and catch the first fish that comes up. You’ll find a coin in its mouth. Give it to them to pay the tax for me and you.”
