In Exodus during the Passover hyssop is used to dip in the blood and strike the door post and lintel and in John hyssop is used to put the sponge with vinegar to Jesus mouth while on the cross. See the verses below: (Exo 12:22) And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning. (Joh 19:29) Now there was set a vessel full of vinegar: and they filled a spunge with vinegar, and put it upon hyssop, and put it to his mouth. I understand that every scripture in the OT points towards Christ and his sacrifice on the cross. So now my question. What is the connection between the hyssop in Exodus 12:22 and John 19:29?
