O Key of David, and scepter of the house of Israel, who opens and no man shuts, who shuts and no man opens: come, and bring forth the captive from his prison, he who sits in darkness and in the shadow of death.
O come, thou Key of David, come,
And open wide our heavenly home;
Make safe the way that leads on high,
And close the path to misery.
As usual, good reflections here.
