4. That he shall have a throne, and be both priest and king upon his throne. A throne denotes both dignity and dominion, an exalted honour with an extensive power. (1.) This priest shall be a king, and his office as a priest shall be no diminution to his dignity as a king: He shall sit and rule upon his throne. Christ, as a priest, ever lives to make intercession for us; but he does it sitting at his Father's right hand, as one having authority, Heb. viii. 1. We have such a high priest as Israel never had, for he is set on the right hand of the throne of the Majesty in the heavens, which puts a prevailing virtue into his mediation; he that appears for us within the veil is one that sits and rules there. Christ, who is ordained to offer sacrifices for us, is authorized to give law to us. He will not save us unless we be willing that he should govern us. God has prepared him a throne in the heavens; and, if we would have any benefit by that, we must prepare him a throne in our hearts, and be willing and glad that he should sit and rule upon that throne; and to him every thought within us must be brought into obedience. (2.) This king shall be a priest, a priest upon his throne. With the majesty and power of a king, he shall have the tenderness and simplicity of a priest, who, being taken from among men, is ordained for men, and can have compassion on the ignorant, Heb. v. 1, 2. In all the acts of his government as a king he prosecutes the intentions of his grace as a priest. Let not therefore those that are his look upon his throne, though a throne of glory and a throne of judgment, with terror and amazement; for, as there is a rainbow about the throne, so he is a priest upon the throne.
