Isaiah 22:23

(23) I will fasten him as a nail in a sure place . . .—The word for “nail” is used both for the peg that fastens a tent to the ground, as in the “stakes” of Isaiah 33:20; Isaiah 54:2; Judges 4:21, or, as in Ezekiel 15:3, for a nail driven into the wall. Here the context shows that the latter meaning is preferable. It was, as the sequel shows, a symbol of the support upon which others can depend. (Comp. the “nail in his holy place” of Ezra 9:8.)

He shall be for a glorious throne . . .—Another symbol of sovereignty follows. The form, throne of glory, is found in its highest application in 1 Samuel 2:8, and Jeremiah 14:21; Jeremiah 17:12. Such a throne, kingly in its state, is to be the pride of the hitherto obscure house of Eliakim.
