What does John 19:29 mean?
What John describes here as "sour wine" may be an especially strong alcohol, or vinegar mixed with water. This may or may not be the same liquid which Jesus refused when He was first put on the cross (Matthew 27:34). Knowing He is seconds away from death (John 19:28), He would no longer have to worry about any numbing effects of the drink. Another possibility is that this unpleasant substance is being given to Jesus as a form of torment: one last sneer from His executioners.John connects this moment to Psalm 69:21, much as he saw prophecy fulfilled when soldiers gambled for Jesus' clothes (John 19:24; Psalm 22:18).
Hyssop has a spongy quality, so it might have been used to offer Jesus a drink without having to hold up the entire jar. Contrary to popular culture, crucifixion victims were not usually lifted far above the ground. The hyssop branch mentioned here was probably less than two or three feet long.
