Christ Who Opens And Shuts

Isa 22:20 And it shall come to pass in that day, that I will call my servant Eliakim the son of Hilkiah:
Isa 22:21 And I will clothe him with thy robe, and strengthen him with thy girdle, and I will commit thy government into his hand: and he shall be a father to the inhabitants of Jerusalem, and to the house of Judah.
Isa 22:22 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.
Isa 22:23 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.
