Psalm 69:23
21 They put bitter poison into my food, and to quench my thirst they give me vinegar to drink. 22 May their dining table become a trap before them. May it be a snare for that group of friends. 23 May their eyes be blinded. Make them shake violently. 24 Pour out your judgment on them. May your raging anger overtake them. 25 May their camp become desolate, their tents uninhabited.
LXX Psalms 68:23
21 They gave me also gall for my food, and made me drink vinegar for my thirst. 22 Let their table before them be for a snare, and for a recompence, and for a stumbling-block. 23 Let their eyes be darkened that they should not see; and bow down their back continually. 24 Pour out thy wrath upon them, and let the fury of thine anger take hold on them. 25 Let their habitation be made desolate; and let there be no inhabitant in their tents:
Notes and References
"... As was the case in Romans 10:19-21, so also here each passage plays an important role in shaping Paul’s reading of the other. By means of Isaiah’s (“spirit of stupor”), Paul transmutes Moses’ lament that God has not yet granted Israel an understanding heart into the much stronger claim that God has, in fact, directly caused Israel’s spiritual insensibility. (The wording “eyes such as do not see ... ears such as do not hear” may reflect Paul’s desire to connect this citation with the words of “David” that follow in Romans 11:9-10 (compare Romans 11:10 / Psalm 68:24 LXX) And it is Deuteronomy’s insistence that their blindness persists “to the present day” that gives Paul interpretive leverage to read the description of Isaiah’s opponents in Isaiah 29:10 as a diagnosis of his contemporaries’ failure to believe the gospel ..."
