Hyssop

Vine's Expository Dictionary of NT Words

1: ὕσσωπος

(Strong's #5301 — Noun Feminine — hussopos — hoos'-so-pos )

a bunch of which was used in ritual sprinklings, is found in Hebrews 9:19; in John 19:29 the reference is apparently to a branch or rod of "hyssop," upon which a sponge was put and offered to the Lord on the cross. The suggestion has been made that the word in the original may have been hussos, "a javelin;" there seems to be no valid reason for the supposition.
