What was Jesus offered to drink at the cross: vinegar with gall, wine with myrrh, or plain vinegar?

The Gospels describe three offers at three different times, not one. The first came as Jesus arrived at Golgotha, before he was nailed to the cross: wine with something bitter in it, which he tasted and refused (Matthew 27:34; Mark 15:23). A Jewish custom recorded in the Talmud, based on Proverbs 31:6, was to give a condemned man drugged wine to dull his senses. Mark names the drug, myrrh. Matthew calls it ‘gall’ (cholē), a word the Greek Old Testament uses for bitter things such as wormwood, to echo Psalm 69:21, “They gave me also gall for my meat; and in my thirst they gave me vinegar to drink”. Many of the oldest manuscripts of Matthew read ‘wine’ (oinos) here rather than ‘vinegar’ (oxos), and the BSB follows them; in any case the ‘vinegar’ of the KJV was the cheap sour wine that soldiers drank, so ‘wine’ and ‘vinegar’ are not two different drinks.

The second offer was mockery during the hours on the cross: the soldiers came up offering him their sour wine (Luke 23:36). The third came at the end, when Jesus said “I thirst”: someone soaked a sponge in the sour wine, put it on a stalk of hyssop or a reed, and held it to his lips, and this time he took it (John 19:28–30; Matthew 27:48; Mark 15:36). The hyssop is what the sponge was lifted on, not something mixed into the drink.
