O Clavis David or O Key of David (December 20)
O Key of David, (Isaiah 22:22; Revelation 3:7)
and Scepter of the house of Israel (Numbers 24:17): You open and no man closes; you close and no man opens (Isaiah 22:22). * Come, and deliver him from the chains of prison who sits in darkness and in the shadow of death (Ps 107:10).
