Tying together Jonah 1 and 2

— Jonah sent to Nineveh (1:1-2)
—— Jonah goes to sea – boards a ship (1:3)
——— Jonah in the belly of the ship; the sailors cry to their gods (1:4-6)
———— Jonah tells the sailors that he worships the one true God (1:7-10)
———— The sailors worship the one true God (1:11-16)
——— Jonah in the belly of the fish; Jonah cries to his God (1:17-2:9)
—— Jonah back on land (2:10)
— Jonah sent to Nineveh (3:1)

Corroborates my suspicion that Jonah’s ministry to the sailors is very important to these chapters
