'Shade' in the Bible

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

And Jehovah God prepared a gourd, and made it to come up over Jonah, that it might be a shade over his head, to deliver him from his evil case. So Jonah was exceeding glad because of the gourd.
