The four-drachma coin probably is a Tyrian stater, precisely enough to pay two persons' temple dues (Avi-Yonah 1974-1976:60-61). Following an old Greek story, some Jewish stories of uncertain date speak of God blessing pious people by leading them to find precious objects in fish (Bultmann 1968:238; Jeremias 1971:87). If Peter knew of such stories, the moral of Jesus' causing him to find money in a fish would not be lost on him. This is irony of a sort: the King's children can pay the tax because the King gives them the money to do so (Patte 1987:247). Jesus can take care of his people who walk close to him.
