O Key of David

O Key of David, O royal power of Israel
controlling at your will the gate of heaven:
come, break down the prison walls of death
for those who dwell in darkness and the shadow of death;
and lead your captive people into freedom.

--Vespers antiphon

O come, thou key of David, come,
And open wide our heav’nly home,
Make safe the way that leads on high,
That we no more have cause to sigh.

--Latin hymn – ninth century
