Matthew Poole and continuators on John 19:29

29 Now there was set a vessel full of vineger: And they filled a spunge with vineger, and put it upon hyssope, and put it to his mouth .

David said, Psal. 69.21. to signifie his enemies multiplying afflictions upon him, They gave me also gall for my meat, and in my thirst they gave me vineger to drink; which he spake metaphorically; part of these words were without a figure literally fulfilled in Christ, who was the Son of David; for he crying out upon the Cross that he thirsted, there being no other liquor at hand, or this being set on purpose for this end, they dip a spunge in it, and give it to him to drink; whither to stupifie his senses, or to prolong his life in those torments, or barely to quench his thirst, is hard to determine. It is probable, that it was such a kind of refreshment as they allowed to ordinary malefactors in his circumstances, the particulars of which usage we are not able to determine.
