“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.” (Isaiah 22:22-23)

This prophecy was originally applied to Eliakim, the keeper of the treasuries in the reign of King Hezekiah. The wearing of the key to the treasuries on his shoulder was symbolic of authority. Isaiah, in fact, had used this same symbol in his great prophecy of the coming Messiah, saying that “unto us a son is given: and the government shall be upon his shoulder” (Isaiah 9:6).

Eliakim thus became a type of Christ in his capacity to open and shut doors with his special key. The Lord Jesus quoted from this passage in His promise to the church at Philadelphia: “These things saith…he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth; I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name” (Revelation 3:7-8). This strong assurance has been a great bulwark to many who were trying to maintain a true witness during times of opposition and suffering.

But Eliakim was also called “a nail in a sure place,” and in this also he was a wonderful type of Christ. Eliakim was trustworthy in his office, and so is Christ. The nail in a sure place speaks of stability in time of trouble, as Ezra later said, “Now for a little space grace hath been shewed from the LORD our God…to give us a nail in his holy place” (Ezra 9:8). Eventually, of course, Eliakim’s nail had to be removed (Isaiah 22:25), but never that of Christ, for He is “an anchor of the soul, both sure and stedfast” (Hebrews 6:19) who will never fail. HMM
