Isaiah 22:22-25. “And the key of the house of David will I lay upon his shoulder: so he shall open, and none shall shut: and he shall shut, and none shall open. And I will fasten him as a nail in a sure place; and he shall be for a glorious throne to his father’s house. And they shall hang upon him all the glory of his father’s house, the offspring and the issue, all vessels of small quantity, from the vessels of cups, even to all the vessels of flagons. In that day, saith the Lord of hosts, shall the nail that is fastened in the sure place be removed and be cut down, and the burden that was upon it shall be cut off: for the Lord hath spoken it.”
There’s a lot going on here. First, it was common for Oriental keys to be large, and often carried on the shoulder. The possession of a key was evidence of property or trust, an emblem of authority.
It was customary to build certain pegs into the house, to hang things on. Unlike temporary nails in plastered wall which can fall out overtime, these were very permanent. On such pegs trophies, shields, swords, gold and silver vessels, changes of raiment, and other valuable things were hung, for show.
Now, on to prophecy. Just as Shebna’s place would be filled by Eliakim, so Antichrist’s place will be filled by Messiah. Eliakim is marked as a type of Christ in vv. 22-24. Christ Himself , in Rev. 3:7, refers to the key of David in these same terms. I am reminded of the words “And the government shall be upon His shoulder” in Is. 9:6.
The honor and responsibility that Messiah will have will far exceed what Antichrist had, just as Eliakim will far exceed Shebna. And we need to remember that it was pride and self-glorification that defeated Shebna, just as it is pride and self-glorification that will defeat Antichrist.
