Then Jonah prayed to Yahweh, his God, out of the fish's belly.
Critics will have their way, however, and one of the strategies is to date all of the Psalms at a point long after Jonah lived, but we shall not play games with dating Old Testament Scriptures.  If the Psalms are later than Jonah, then the Psalmist was influenced by the Prophet!  And, as Deane said, "It is a matter of controversy, incapable of settlement, whether Jonah or the Psalmist is the original!"[8]
