The key to the house of David and look the one who made it

Isaiah 22:1-25
 A prophecy against the Valley of Vision.
You built a reservoir between the two walls for the water of the Old Pool, but you did not look to the One who made it, or have regard for the One who planned it long ago.
But see, there is joy and revelry, slaughtering of cattle and killing of sheep, eating of meat and drinking of wine! Let us eat and drink,” you say, “for tomorrow we die!”
the Lord Almighty, says: Beware, the Lord is about to take firm hold of you and hurl you away, you mighty man. He will roll you up tightly like a ball and throw you into a large country. There you will die and there the chariots you were so proud of will become a disgrace to your master’s house.
In that day I will summon my servant, Eliakim son of Hilkiah.  I will place on his shoulder the key to the house of David; what he opens no one can shut, and what he shuts no one can open. I will drive him like a peg into a firm place; he will become a seat of honor for the house of his father. 
Jerusalem was Isaiah's home. It was here that he had his visions. The city is surrounded by valleys and mountains. The 'Vaeely of Vision' which stands for the city is probably the Hinnom Valley. Despite the reprieve in Hezekiah's day. Isaiah foresees the future destruction of Jerusalem.
The people's reaction in the face of disaster is a mixture of frenzied activity and sheer escapism. They check their weapons and store water against a siege, but they do not 'look to the Maker of the city'.
Verse 15 relate to Isaiah's own day. Shebna, a high official in Hezekiah's court is to be demoted, and Eliakim promoted. But he will find himself unable to cope with his hangers-on, and his authority will be short-lived. 
Why?
No matter under good situation or face trouble, the only way is to look on the One who made it. The Lord Almighty.
Who is promoted or demoted is the authority of the Lord. What my situation could be is in hands of the Lord.
How?
Look on the One who made it.
