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.
Instrument of Jesus' crucifixion
Like the Epistle of Barnabas, Justin saw the stretched-out hands of Moses in the battle against Amalek as foreshadowing the cross of Jesus: "If he gave up any part of this sign, which was an imitation of the cross (σταυρός), the people were beaten, as is recorded in the writings of Moses; but if he remained in this form, Amalek was proportionally defeated, and he who prevailed prevailed by the cross (σταυρός). For it was not because Moses so prayed that the people were stronger, but because, while one who bore the name of Jesus (Joshua) was in the forefront of the battle, he himself made the sign of the cross (σταυρός)."
