Contradiction with Jonah 4:6
Jonah 4:6 states that God prepared a gourd to provide shade for Jonah, which contrasts with Jonah 4:7, where God prepares a worm to destroy the gourd.
Jonah 4:6: And the LORD God prepared a gourd, and made [it] to come up over Jonah, that it might be a shadow over his head, to deliver him from his grief. So Jonah was exceeding glad of the gourd. [gourd: or, palmcrist: Heb. Kikajon] [was...: Heb. rejoiced with great joy]
