Passage
And I--with a voice of thanksgiving--I sacrifice to Thee, That which I have vowed I complete, Salvation <FI>is<Fi> of Jehovah.
And I--with a voice of thanksgiving--I sacrifice to Thee, That which I have vowed I complete, Salvation <FI>is<Fi> of Jehovah.
Jonah 2:7 In the feebleness within me of my soul Jehovah I have remembered, And come in unto Thee doth my prayer, Unto Thy holy temple.
Jonah 2:8 Those observing lying vanities their own mercy forsake.
Jonah 2:9 And I--with a voice of thanksgiving--I sacrifice to Thee, That which I have vowed I complete, Salvation <FI>is<Fi> of Jehovah.
Jonah 2:10 And Jehovah saith to the fish, and it vomiteth out Jonah on the dry land.
The verse centers on "i--with", "voice", "thanksgiving--i", "sacrifice", "thee", "vowed", "complete", and "salvation". It is saying that the verse draws attention to "i--with" and "voice", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "Those observing lying vanities their own mercy..." into verse 10's "And Jehovah saith to the fish and...", so "i--with" and "voice" belong inside that flow. In Jonah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "i--with" and "voice" with trust shaped by these words, not by a vague optimism outside the passage.
