Matthew Poole and continuators on Jonah 4:5

5 So Jonah went out of the city and sate on the east-side of the city , and there made him a booth , and sat under it in the shadow , till he might see what would become of the city .

When the Lord had taken notice and reproved the passions of Ionah, and made some impression on his mind for the present.

Discontented in himself, and doubtful of the issue whether God would be more tender of the life of multitudes or of Ionah's Credit, the Prophet withdrew himself, and waits, How long we have not any ground of conjecture.

Put himself into a posture of waiting, and therefore to repose himself, rather sat than stood.

Which in likelihood was some higher ground, the City standing on the East-banks of Tygris, the farther he went East the higher the ground was, and the safer from the uncertain manner of the Cities overthrow.

Some small and mean shed for shade and shelter usually made of green boughes.

These boughes thus pitch'd and made into a Booth afforded some shadow in which Ionah reposed himself.

By this passage it should seem the forty dayes were not fully expir'd nor yet wanted much of expiring, and Ionah seems resolved there to expect the event of the City.
