Coin in the fish's mouth

[5] Heinrich Meyer suggests that Peter's assertion "Yes" makes it "clear that Jesus had hitherto been in the habit of paying the tax".

Jesus typically performed miracles and made statements that were offensive to his audience, particularly the Jewish priesthood.

The coin in the fish's mouth is generally seen as a symbolic act or sign, but there is little agreement concerning what it signifies.

Pompey subsequently overthrew Jerusalem, and made Judea under subjection to Rome, with an annual tribute.

However, after the rebellion, when Jerusalem was captured by Vespasian, the temple was destroyed, and he ordered them to pay the didrachma to the Roman capitol.

This sentiment around the time of Christ, resulted in the sect of the Galilæans, led by Judas of Galilee, who refused to pay tribute to Caesar.

St. Jerome, Bede and others are of the opinion that in order therefore that Christ might show the baselessness of this charge, he paid the didrachma.
