Psalms 69:20-22

Verse 21

They gave me also gall for my meat - Even the food, necessary to preserve us in their slavery, was frequently mingled with what rendered it unpleasant and disgusting, though not absolutely unwholesome. And vinegar, sour small wines, was given us for our beverage. This is applied to our Lord, Mat 27:34, where the reader is requested to consult the notes.
Verse 22

Let their table become a snare - The execrations here and in the following verses should be read in the future tense, because they are predictive; and not in the imperative mood, as if they were the offspring of the psalmist's resentment: "Their table Shall become a snare; - their eyes Shall be darkened; - thou Wilt pour out thine indignation upon them; - thy wrathful anger Shall take hold of them; - their habitation Shall be desolate, - and none Shall dwell in their tents."

The psalmist prophesies that the evils which they had inflicted on the Israelites should be visited on themselves; that as they had made them eat, drink, labor, and suffer, so God should in his judgment treat them.
