“I will place on his shoulder
The key of the house of David.
He shall open.
No one shall shut.
He shall shut.
No one shall open.
I will fasten him
Like a peg in a secure place.
He will become a throne of honor
To his ancestral house.
They will hang on him
The whole weight
Of his ancestral house,
The offspring,
The issue,
Every small vessel,
From the cups to all the flagons.”
Somehow, Eliakim had a special key to the house of David. This almost seems like a royal power. He was then able to open and shut things. When he opened or shut something, no one else could do the opposite. So that as the master of the royal house, he had the keys to the house that no one else could use. Eliakim himself was to be pegged in a secure place since he had some kind of throne of honor from his ancestral house. He would carry the whole weight of his family and their offspring. He was in charge of everything from small cups to large bottles or flagons.
