Jonah 2 - A sign......

Old John Gill writes....

In this Jonah was a type of Christ, who, amidst his agonies, sorrows, and sufferings, prayed to his Father, and claimed his interest in him as his God, Heb 5:7. What follows contains the sam and substance of the prophet's thoughts, and the ejaculations of his mind, when in the fish's belly; 

but were not put up in this form, but were reduced by him into it after he was delivered; as many of David's psalms were put into the form and order they are after his deliverance from troubles, suitable to his thoughts of things when he was in them; 

and indeed the following account is an historical narration of facts, which were before and after his prayer, as well as of that itself.

Jesus has said..

Mat 16:4  A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas. And he left them, and departed.

Mat 12:38  Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.

Mat 12:39  But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:

Mat 12:40  For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.

Mat 12:41  The men of Nineveh shall rise in judgment with this generation, and shall condemn it: because they repented at the preaching of Jonas; and, behold, a greater than Jonas ishere.

Mat 12:42  The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here.

Jonah's Prayer

Jon 2:1  Then Jonah prayed unto the LORD his God out of the fish's belly,

Jon 2:2  And said, I cried by reason of mine affliction unto the LORD, and he heard me; out of the belly of hell cried I, and thou heardest my voice.

Jon 2:3  For thou hadst cast me into the deep, in the midst of the seas; and the floods compassed me about: all thy billows and thy waves passed over me.

Jon 2:4  Then I said, I am cast out of thy sight; yet I will look again toward thy holy temple.

Jon 2:5  The waters compassed me about, even to the soul: the depth closed me round about, the weeds were wrapped about my head.

Jon 2:6  I went down to the bottoms of the mountains; the earth with her bars was about me for ever: yet hast thou brought up my life from corruption, O LORD my God.

Jon 2:7  When my soul fainted within me I remembered the LORD: and my prayer came in unto thee, into thine holy temple.

Jon 2:8  They that observe lying vanities forsake their own mercy.

Jon 2:9  But I will sacrifice unto thee with the voice of thanksgiving; I will pay that that I have vowed. Salvation is of the LORD.

Jon 2:10  And the LORD spake unto the fish, and it vomited out Jonah upon the dry land.
