John 19:29

Evidently it was customary to offer wine vinegar (Gr. oxos) to the victims of crucifixion since John described the jar of it as "standing there" or "set there." Only John mentioned that the soldiers put the sponge soaked with wine vinegar on a branch of hyssop that they extended to Jesus. Hyssop was readily available since it grew out of many rocky crevices as a weed. The hyssop reference may simply be a detail in the testimony of an eyewitness to Jesus’ crucifixion. However, it may hint at Jesus being the Lamb of God since the Jews used hyssop to sprinkle blood on their doorposts and lintels at Passover (cf. Exodus 12:22; 1 Corinthians 5:7). The sponge was evidently small enough so Jesus could put at least some of it in His mouth. The hyssop branch was obviously strong enough to remain erect under the sponge’s weight. Jesus was probably not extremely high above ground level as He hung on the cross, many famous paintings notwithstanding (cf. John 3:14).
