3:1-5 God again commands Jonah to go to Nineveh to proclaim the message of God. This time, Jonah obeys God and goes to Nineveh. Nineveh was so huge that it required three days to get through it and reach the city. Jonah pronounces eight words that are recorded and the Ninevites believed. They started to fast and put on sackcloth to prove their repentance and sorrow. 

3:6-9 The king is even depicted as believing in God. The highest power in the city is now humbling himself before God and heeds the warning of God. This is something Israel failed to do time and time again. Then the king issues a decree that requires 4 things of the people of Nineveh:

1. Do not eat or drink (animals too)
2. Cover with sackcloth (animals too)
3. Call upon God
4. Repent

3:10 God saw that the people, including the king, were serious about what they were doing. They had really turned from their ways of evil and wickedness and so God did not bring disaster to them. He had compassion on them. This is an enemy city of Israel, and yet God still had compassion on them. This event shows the immense amount of compassion and love God has for all people.
