The stated goal is practical: shade “over his head,” giving relief from Jonah’s misery or discomfort. The effect is immediate in Jonah’s emotions: he becomes extremely happy, and the text ties that happiness specifically to the plant.

Where interpretation differs (only where needed)

What kind of plant is meant. Some think the Hebrew term refers to a castor oil plant; others favor a kind of gourd or vine. In this verse, the exact species does not change the basic point that God provides fast, protective shade.

How strong “deliver him” is. Some read “deliver” as meaning Jonah was in real danger (such as heatstroke risk) and God rescued him from harm. Others read it as relief from irritation and physical misery rather than a life-threatening crisis. Either way, the text emphasizes bodily relief.

Why the disagreement exists

The Hebrew word for the plant (qiqaion) is uncommon, so translators and interpreters compare ancient translations and likely regional plants. Also, the phrase “deliver him from his discomfort” can refer either to serious danger or to intense distress, and the verse itself does not spell out the degree.

What this passage clearly contributes

Explicitly, the verse contributes that God intentionally arranges created things to affect human experience (here: shade and comfort). It also highlights Jonah’s emotional pattern: he can be intensely upset about what God does (earlier) and intensely delighted when his own comfort improves. The narrative uses a simple, physical need to expose what Jonah is responding to most strongly in this moment (his personal relief), setting up the next steps in the story (vv. 7–11).
