Why did God spare Nineveh?

The city turns

Jonah’s warning offered no way out (his five-word message). Nineveh looked for one anyway. “The people of Nineveh believed God” (Jonah 3:5), with the same Hebrew verb Genesis uses when Abraham “believed in Yahweh” (Genesis 15:6). They fasted and put on sackcloth, “from their greatest even to their least.” The king took off his royal robe, sat in ashes and sent out a decree.

but let them be covered with sackcloth, both man and animal, and let them cry mightily to God. Yes, let them turn everyone from his evil way and from the violence that is in his hands.

Violence, hamas in Hebrew, is the very sin that brought the flood (Genesis 6:11). The rabbis took the line about hands literally. In the Talmud, Shmuel teaches that even a Ninevite who had stolen a beam and built it into his palace would tear the palace down to give the beam back (Taanit 16a). Repentance meant restitution, not only tears.

Why the animals wore sackcloth

The decree includes the herds and flocks: no food, no water, sackcloth for “both man and animal.” It sounds strange to us, but not to the ancient world. Herodotus says that Persian soldiers mourning their general Masistius shaved the manes of their horses and pack animals (Histories 9.24). The book of Judith, read in Catholic and Orthodox Bibles, has the people of Jerusalem put sackcloth even on their cattle (Judith 4:10). Animals belonged to the household, and the whole household mourned.

Not every reader was moved. In the Jerusalem Talmud, Rabbi Shimon ben Lakish calls it a clever trick: the Ninevites shut calves away from their mothers so both would bellow, and told God that if he had no pity on them, they would have none on the animals (Taanit 2:1). The book itself takes the animals seriously. Its very last words, in Hebrew, are “and many animals.”

God’s reasons

God relented, and Jonah exploded: he had known all along that God is “gracious and merciful” (why he ran). He sat outside the city, glad of a vine that shaded him, until a worm killed it. Then God gave the reason that ends the book.

You have been concerned for the vine, for which you have not labored, neither made it grow; which came up in a night and perished in a night. Shouldn’t I be concerned for Nineveh, that great city, in which are more than one hundred twenty thousand persons who can’t discern between their right hand and their left hand, and also many animals?

The argument runs from small to great: you grieved for a plant you never planted; may I not grieve for a city I made? People who cannot tell right from left may be small children, or adults who never had the chance to know better. Either way, ignorance pleads for them. The prophet Ezekiel puts the same principle in God’s mouth: “Have I any pleasure in the death of the wicked?” What God wants, he says, is that the wicked turn and live (Ezekiel 18:23).

Did Nineveh really repent?

No Assyrian record mentions it, and the book never names the king, calling him only “king of Nineveh,” an odd title for rulers who styled themselves king of Assyria. Historians note that Assyria had a frightening decade in the 760s BC: revolts, plague and a total eclipse of the sun on June 15, 763 BC, all listed in its own records. A scared city might have listened. Many scholars read Jonah as a teaching story written later, about a God whose mercy reaches even Israel’s enemies. Traditional Jewish and Christian readers take it as history, and Jesus spoke of the Ninevites who “repented at the preaching of Jonah” (Matthew 12:41). The reprieve was not forever: see when Nineveh was destroyed.
