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

    (a) Being now swallowed up by death, and seeing no remedy to
        escape, his faith broke out to the Lord, knowing that
        out of this very hell he was able to deliver him.

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

    (b) For he was now in the fishes belly as in a grave or
        place of darkness.

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

    (c) This declared what his prayer was, and how he laboured
        between hope and despair, considering the neglect of his
        vocation, and God's judgments for it: but yet in the end
        faith gained the victory.

Jon 2:6
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 {d} life from corruption, O LORD my God.

    (d) You have delivered me from the belly of the fish and all
        these dangers, as it were raising me from death to life.

Jon 2:8
2:8 They that observe lying {e} vanities forsake their own {f}
    mercy.

    (e) Those that depend upon anything except on God alone.
    (f) They refuse their own felicity, and that goodness which
        they would otherwise receive from God.
