A third important title, "Son of Man", has its roots in Ezekiel, the Book of Enoch, (a popular Jewish apocalyptic work of the period), and especially in Daniel 7:13–14, where the Son of Man is assigned royal roles of dominion, kingship and glory. Mark 14:62 combines more scriptural allusions: before he comes on clouds (Daniel 7:13) the Son of Man will be seated on the right hand of God (Psalm 110:1), pointing to the equivalence of the three titles, Christ, Son of God, Son of Man, the common element being the reference to kingly power.
