Nativity detail GDavid.jpgO Clavis David, et sceptrum domus Israel; qui aperis,
et nemo claudit; claudis, et nemo aperit: veni, et educ vinctum de domo
carceris, sedentem in tenebris, et umbra mortis.

O Key of David and Sceptre of
the House of Israel, who opens and no one can shut, who shuts and no one can open
(Is 22:22; Rev 3:7): Come and bring the prisoners forth from the prison cell, those
who dwell in darkness and the shadow of death (Is 42:7; Ps 106:13-14; Lk 1:9)

For Jews reading (hearing) this will notice that Jesus makes the claim that he is God, precisely for us, the Son of God, the Second Person of the Most Blessed Trinity. The image of the “Key of David” is a clear indication of God and His holy name. As Pius Parsch reminds us, “It should, then, be perfectly obvious that Christ is the “Key of David,” i.e., the One who opens all the secrets and mysteries of the Old Testament. The sceptre implies a true fullness of power over God’s kingdom.”
