The Key of David

In that day I will call my servant Eliakim the son of Hilkiah, and I will clothe him with your robe, and will bind your sash on him, and will commit your authority to his hand. And he shall be a father to the inhabitants of Jerusalem and to the house of Judah. And I will place on his shoulder the key of the house of David. He shall open, and none shall shut; and he shall shut, and none shall open. And I will fasten him like a peg in a secure place, and he will become a throne of honor to his father’s house. And they will hang on him the whole honor of his father’s house, the offspring and issue, every small vessel, from the cups to all the flagons. In that day, declares the LORD of hosts, the peg that was fastened in a secure place will give way, and it will be cut down and fall, and the load that was on it will be cut off, for the LORD has spoken.” Isaiah 22:20-25

For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the increase of his government and of peace there will be no end, on the throne of David and over his kingdom, to establish it and to uphold it with justice and with righteousness from this time forth and forevermore. The zeal of the LORD of hosts will do this. Isaiah 9:6-7
