“... The last example is in vs 10b. Two changes are made here. First, καὶ ἐξομολογήσεως (“and of thanksgiving”) is inserted after αἰνέσεως (“of praise”) creating the hendiadys αἰνέσεως καὶ ἐξομολογήσεως which commonly occurs in the Greek Psalter. Its addition does not substantially alter the meaning, but adds a pious note to Jonah’s affirmation. The second change is more dramatic. In the Masoretic Text the last two words of the Psalm are a nominal clause pronouncing that “salvation belongs to Yahweh” (יְשׁוּעָתָה לַיהוָה). The translator apparently did not observe this syntactical relationship and has made τῷ κυρίῳ (לַיהוָה) the indirect object of ἀποδώσω (אֲשַׁלֵּמָה “I will pay”) and (יְשׁוּעָתָה) an adverbial modifier: ὅσα ηὐξάμην ἀποδώσω εἰς σωτηρίαν μου τῷ κυρίῳ = “What I have vowed, I will repay for my salvation to the Lord.” In the Septuagint version, Jonah promises that he will obey the Lord because he now realizes that such obedience is the only route through which rescue will be achieved.
