And ye shall be unto me a kingdom of priests
Instead of being in a state of servitude and bondage, as they had been in Egypt, they should be erected into a kingdom, become a body politic, a free state, a commonwealth governed by its own laws, and those laws of God's making; yea, they should be a kingdom to him, and he be more immediately the king of them, as he was not of others, the government of Israel being a Theocracy; and this kingdom should consist of men that were priests, who had access to God, served him, and offered sacrifice to him; or of men greatly esteemed and honoured, as priests were in those times. Jarchi interprets it, a kingdom of princes, as the word sometimes signifies: the subjects of this kingdom were princes, men of a princely spirit, and these princes, like those of the king of Babylon, who boasted they were altogether kings; and like the Roman senators, of whom the ambassador of Pyrrhus said, that he saw at Rome as many kings as he saw senators. And so here all the Targums render it, "kings and priests": to which reference seems to be had not only in ( 1 Peter 2:9 ) but in ( Revelation 1:6 ) , they were kings when they got the victory, as in the times of Joshua, over the several kings of Canaan, and had their kingdoms divided among them; and before the priesthood was settled in the family of Aaron, every head of a family in Israel was a priest; and they were all priests at the passover, as Philo F9 observes: and so the spiritual Israel of God are kings and priests; they are kings, having the power and riches of kings; having got through Christ the victory over sin, Satan, and the world; and being possessed of the kingdom of grace, and heirs of the kingdom of glory; and priests, being allowed to draw nigh to God, to present themselves, souls and bodies, a holy and living sacrifice, to offer to him the sacrifices of prayer and praise through Christ, by whom they become acceptable to him: "and an holy nation"; being separated from all others, and devoted to the worship and service of God, having holy laws, and holy ordinances, and a holy service, and a holy place to perform it in, and holy persons to attend unto it, as they afterwards had. In allusion to this, the spiritual Israel, or people of God, are also called so, ( 1 Peter 2:9 ) being chosen unto holiness, redeemed from all iniquity, called with an holy calling, sanctified by the blood of Christ, and made holy by the Spirit of God, and under the influence of his grace live holy lives and conversations:
these are the words thou shalt speak unto the children of Israel:
what he would have them do, and they were bound to do in a way of duty to him, and what he in a way of grace would do for them, and they should be unto him,
