Good satire or parody can be hard to detect. The better it is, the more likely it is that someone will take it seriously and won’t get the joke. I well remember when I was a much younger man having a conversation with a good mate about the clichés that were used in church prayers far too often. Between us we came up with an impressive list of all the prayer-clichés we could think of. A few days later my mate’s church had a social function in the church hall and my friend was called on to say grace before dinner. Being young, brash, and a bit of a smart-arse, my friend decided to have some fun while having a pointed poke at what had become a traditional, yet irrelevant style of prayer. He made use of every one of those clichés in a rather lengthy parody of grace before dinner. Later that evening an elderly lady came to him and said “I’ve been a member of this church for forty years, and that was the loveliest prayer I’ve ever heard!” That’s a sign of truly clever parody – people will be divided as to whether it is serious (and in this case pious), or is making a joke at the expense of those who take it seriously.
The royal court scene in Jonah 3 in my view is a case of clever satire (and parody), which commentaries have traditionally interpreted very seriously (while missing the humour, and, therefore, the real point of the story). It must have been the briefest evangelistic campaign in history (Jonah preached for only one day in a city which normally took three days to cross), consisting of just five words (in Hebrew, a few more in English): עֹוד אַרְבָּעִים יֹום וְנִֽינְוֵה נֶהְפָּֽכֶת Forty days more, and Nineveh shall be overthrown! Remarkably, the people responded to this short message by repenting, proclaiming a fast, and putting on sackcloth (Jonah 3:4-5). It’s remarkable for several reasons: Jonah was unheard of in Nineveh, and had only just arrived; being from Israel his message would suggest that the god of tiny Israel was more powerful than all the gods of Nineveh and the mighty Assyrian empire; the five-word message gave no details and no call to repent or opportunity to avert the disaster. News of this reached the king, who immediately responded in much the same way as his people. His response was even more remarkable because he only heard the message second-hand, and was in a much better position to evaluate the likelihood that an unknown preacher from some backwater would know the fate of a great city like Nineveh, soon to be the most powerful city in the world. This is all so astoundingly unlikely the initial readers or listeners of this story would almost certainly have recognised it as humorous.
So the king decided to issue a decree that everyone should fast and put on sackcloth. The problem with this is that everyone had already decided to do just that! His decree would therefore be meaningless, simply ratifying what the masses had already decided. It would confirm that the king wasn’t in control, and that the mob made the rules. Nineveh wasn’t a democracy, and wasn’t about to become one, so the king issued a different decree:
“By decree of the king and his nobles: No man or beast—of flock or herd—shall taste anything! They shall not graze, and they shall not drink water! They shall be covered with sackcloth—man and beast—and shall cry mightily to God. Let everyone turn back from his evil ways and from the injustice of which he is guilty.” (3:8)
The royal decree affirmed what the masses had already decided, but the king extended it to livestock as well! The animals even had to repent from their evil ways and cry out to God! The writer is having a joke at the king’s expense. He makes him out to be powerless – if he can’t rule his own people at least he can issue decrees to dumb cattle. The writer of Jonah has a final punchline right at the end of the book, where God is discussing with the prophet whether or not he should save Nineveh, because, after all, it was a big city with a lot of (dumb) people (because they couldn’t tell one hand from the other) but with “many cattle” (who were smart enough to cry out to God and to repent!) (4:11).
But there’s a twist in the story. When the king issues his decree he adds “Who knows? God may relent and change his mind; he may turn from his fierce anger, so that we do not perish” (3:9). In the words of one biblical scholar, this is “a piece of rather sophisticated theology” . The Ninevite king demonstrated an apparent awareness of Hebrew scripture, or at least the theological issues which gave rise to or came out of those texts, because he uses the specific language of several texts in Deuteronomy, Jeremiah and Chronicles and frames it as a question in an almost identical way to the book of Joel. Is the writer implying that the Ninevite king was familiar with all these biblical texts? The idea is comical, which may very well be the point of the ridiculousness of the allusions.
In using these texts in the way he does, the writer simultaneously ridicules the foreigner and makes his question the central issue of the story. The king would certainly have been unaware of one or other of these texts, yet the writer puts words into his mouth with which the reader or listener would have been familiar, implying that he was aware of the theological discussion about these texts. This is a story-telling device which is used elsewhere in the Hebrew Bible. Nebuchadnezzar is ridiculed on the one hand, but makes profound statements about God on the other. Naaman, a Syrian military commander, was humiliated by the prophet Elisha, but teaches the king of Israel a valuable lesson at the same time (2 Kings 5). It’s a clever device. It’s easy to ridicule a foreigner, but then to have sophisticated theological truths come from their mouths is akin to saying “See, these stupid idol-worshippers get it, why don’t you?” The audience is first softened by the humour, and in doing so the writer/speaker prepares them to be more receptive to the hard-hitting message that follows.
