Then it will come about in that day, That I will summon My servant Eliakim the son of Hilkiah, And I will clothe him with your tunic And tie your sash securely about him. I will entrust him with your authority, And he will become a father to the inhabitants of Jerusalem and to the house of Judah. Then I will set the key of the house of David on his shoulder, When he opens no one will shut, When he shuts no one will open. I will drive him like a peg in a firm place, And he will become a throne of glory to his father’s house.
Who is Eliakim? Frankly I also do not know. From what I found over the internet, he was mentioned in 2 Kings 18:18 and Isaiah 36:3 as an assistant to King Hezekiah. But looking at the verses above, it seems that we can find the shadow of Christ in him.
The above verses were what Isaiah was supposed to tell Shebna, an evil officer (see Isaiah 22:15). Eliakim was to replace Shebna, and we see God’s love for His people that He would always arrange for His servant to take care of His people. Verse 22 mentioned about the key of the house of David, and no one shall shut what Eliakim opens, nor open what Eliakim shuts. This verse is significant because Jesus quoted this to describe His power as mediator (see Rev 3:7). Thus in a way Eliakim was a foreshadow of Christ. The last verse, verse 23, shows that Eliakim would be secure in his position, like a peg fastened in a secure place. Matthew Henry commented this means Eliakim would not be cut down, just like Jesus and His kingdom cannot be shaken.
