Isaiah 22:23

And I will fasten him [as] a nail in a sure place,.... In a strong part of the wall or timber, where it shall not fail, or be removed, or cut down, and so let drop what is hung upon it: it denotes the stability and continuance of his government, and of the strength and support he should be of unto others; and well agrees with Christ his antitype; see Zec 10:4 and is expressive of the strength of Christ, as the mighty God; and as the man of God's right hand, made strong for himself; and as the able Saviour, and mighty Redeemer; and of the stability of his person, he is unchangeable, the same today, yesterday, and for ever; and of his office, as Mediator, Head, and Surety of the covenant; whose priesthood passes not from one to another, and whose kingdom is an everlasting one, and his truths and ordinances unshaken and immovable: the sure place in which he is fixed is both his church, where he is the everlasting Head, Husband, and Saviour of it; and heaven, where he is, and will be retained, until the time of the restitution of all things:and he shall be for a glorious throne to his father's house; or make the throne of his father's house glorious, Eliakim being, as some have thought, of the blood royal; or he should be an honour and credit to his father's house, by his wise and faithful administration of the government committed to him.
