Matthew Poole and continuators on Jonah 2:1

1 THen Jonah prayed unto the LORD his God out of the fishes belly .

And, Hebr. at that time when he lay by the heels a close Prisoner in a Prison, whence none before or since ever came out alive.

Sent his Petition in all humble and submissive manner unto God; Jonah wonderfully preserved alive, and in full exercise of his judgment and memory now betakes himself to Prayer, and in this exerciseth his Graces; his soul follows hard after God, when he was shut up in this Dungeon.

That was angry, and now was punishing of Jonah, the Lord who had committed him to this Prison. The Almighty God, who can do for Jonah all that he can need or desire.

Though Jonah in his froward fit flies from his God, yet now by the rod taught better he flyes to God, nay as his God, and remembers his particular interest in God. If Jonah prayes by Faith grounded on God's Almightiness, now he prayes with assurance and hope of Faith, looking to God as his God; if the Power of the Lord and his Mercy keep Jonah alive in the fishes belly, the same Power and Mercy can deliver him out of this danger, and the Prophet believes he is kept there for an enlargement, as miraculous as his confinement was;

where he was a Prisoner under many miracles, and all concur to awaken him to Prayer and Faith; he calls it the belly of Hell, or the Grave; ver. 2. implyed his time well there.
