O Clavis 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.” Isaiah had prophesied, AI will place the Key of the House of David on His shoulder; when he opens, no one will shut, when he shuts, no one will open.” (22:22), and “His dominion is vast and forever peaceful, from David’s throne, and over His kingdom, which he confirms and sustains by judgment and justice, both now and forever.” (9:6).
