Paragraph Titles
In order to improve the quality of how you read, when you are reading Jonah start to create one sentence titles for every paragraph. This can be time consuming but it is beneficial to understand the layout of the book.
For Example
Then the word of the Lord came to Jonah the second time, saying, 2 “Arise, go to Nineveh, that great city, and call out against it the message that I tell you.” 3 So Jonah arose and went to Nineveh, according to the word of the Lord. Now Nineveh was an exceedingly great city, three days' journey in breadth. 4 Jonah began to go into the city, going a day's journey. And he called out, “Yet forty days, and Nineveh shall be overthrown!” 5 And the people of Nineveh believed God. They called for a fast and put on sackcloth, from the greatest of them to the least of them. - Jonah 3:1-5
A paragraph title for this could be "Jonah goes to Nineveh and calls them to repentance."
