Psalm 68:21-22
My heart hath expected reproach and misery; and I looked for one that would grieve together with Me, but there was none: I sought for one that would comfort Me, and I found none; and they gave Me gall for My food, and in My thirst they gave Me vinegar to drink.

Verse 21. Misery. For which I ardently longed, as the Fathers explain it. — None. I expected that my brethren would at least condole with me: but I was deceived. Christ drank the bitter chalice to the dregs, and found no consolation even from his Father. C.
Verse 22. Food. Tert. reads “drink;” which agrees better with gall. Yet it might be mixed with food, (C.) with wine and myrrh, which were given to our Saviour, when he arrived at Calvary, as vinegar was offered to him on the cross. Matt. xxvii. 34. Jo. xix. 28. This was the last prophecy which regarded our Saviour, while living; and was the last instance of the Jewish malice, by which they requited him for the thirst which he had for the salvation of mankind. Greg. Naz. &c. Bert. — Jeremias (viii. 14. and xxiii. 15. and Lam. iii. 15.) uses the same expressions, in a metaphorical sense, to describe the afflictions of the captives. C.

Question V: Whether in appearance the Davidian origin can be denied to those psalms which are cited in the Old and New Testament distinctly under the name of David, among which to be considered before the rest come: psalm 2, Quare fremuerunt gentes; psalm 15, Conserva me, Domine; psalm 17 Diligam te, Domine, fortitudo mea; psalm 31, Beati, Quorum remissae sunt iniquitates; psalm 68, Salvum me fac, Deus; psalm 109, Dixit Dominus Domino meo?–Reply: In the negative.
