I went down to the bottoms of the mountains - This also may be literally understood. The fish followed the slanting base of the mountains, till they terminated in a plain at the bottom of the great deep.
The earth with her bars - He represents himself as a prisoner in a dungeon, closed in with bars which he could not remove, and which at first appeared to be for ever, i.e., the place where his life must terminate.
Yet hast thou brought up my life - The substance of this poetic prayer was composed while in the fish's belly; but afterwards the prophet appears to have thrown it into its present poetic form, and to have added some circumstances, such as that before us; for he now speaks of his deliverance from this imminent danger of death. "Thou hast brought up my life from corruption."

When my soul fainted within me,.... Covered with grief; overwhelmed with sorrow; ready to faint and sink at the sight of his sins; and under a sense of the wrath and displeasure of God, and being forsaken by him:

I remembered the Lord; his covenant and promises, his former mercies and lovingkindness, the gracious experiences he had had of these in times past; he remembered he was a God gracious and merciful, and ready to forgive, healed the backslidings of his people, and still loved them freely, and tenderly received and embraced them, when they returned to him:

and my prayer came in unto thee, into thine holy temple; into heaven itself, the habitation of God's holiness, the temple where he dwells, and is worshipped by holy angels and glorified saints; the prayer the prophet put up in the fish's belly, encouraged to it by remembering the mercy and goodness of God, ascended from thence, and reached the ears of the Lord of hosts in the highest heavens, and met with a kind reception, and had a gracious answer; see Psa 3:4.

bottoms of . . . mountains--their extremities where they terminate in the hidden depths of the sea. Compare , "the foundations of the hills" ().

earth with her bars was about me--Earth, the land of the living, is (not "was") shut against me.

for ever--so far as any effort of mine can deliver me.

yet hast thou brought up my life from corruption--rather, "Thou bringest . . . from the pit" [MAURER]. As in the previous clauses he expresses the hopelessness of his state, so in this, his sure hope of deliverance through Jehovah's infinite resources. "Against hope he believes in hope," and speaks as if the deliverance were actually being accomplished. Hezekiah seems to have incorporated Jonah's very words in his prayer (), just as Jonah appropriated the language of the Psalms.
