o key of david

O Clavis David, and scepter of the house of Israel, who opens and no man shuts, who shuts and no man opens: come, and lead forth the captive who sits in the shadows from his prison.
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 (Isaiah 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 (Isaiah 9:6).
