Holy Lance
A Holy Lance is conserved in Vagharshapat (previously known as Echmiadzin), the religious capital of Armenia. It was previously held in the monastery of Geghard. The first source that mentions it is a text "Holy Relics of Our Lord Jesus Christ", in a thirteenth-century Armenian manuscript. According to this text, the spear which pierced Jesus was to have been brought to Armenia by the Apostle Thaddeus. The manuscript does not specify precisely where it was kept, but the Holy Lance gives a description that exactly matches the lance, the monastery gate, since the thirteenth century precisely, the name of Geghardavank (Monastery of the Holy Lance).
Magic sword
The Bible relates in the Book of Genesis how God, seeking to deter Adam and Eve from returning to the Garden of Eden, "placed at the east of the garden of Eden Cherubim and a flaming sword which turned every way". By some accounts, the Cherubim are replaced with the Archangel Michael, who wields a similar weapon.
King David was given the sword of the slain giant Goliath by the priest Ahimelech, to which was attached extra-biblical mythology and traditions.
In the Book of Revelation, Jesus is symbolically described wielding a double-edged sword that proceeds out from his mouth, in reference to the "sword of the spirit" which is the "word of truth".
