“Then Jonah

Went out of the city.

He sat down

East of the city.

He made a booth

For himself there.

He sat under it

In the shade.

He was waiting

To see

What would become

Of the city.”

Jonah then went outside Nineveh on the east side of the city to see what was going to happen.  He made a tent or a booth to get some shade from the sun.  He sat there awaiting the eventual future of the city of Nineveh.
