Holy Lance
The Holy Lance, also known as the Lance of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, according to the Gospel of John, is the lance that pierced the side of Jesus as he hung on the cross.
Sponge (material)
In the New Testament, a Roman soldier offers Jesus Christ a sponge soaked in vinegar on the tip of his spear (some versions say staff) for Jesus to drink during his crucifixion, as an act of mockery.
