And Jehoiada made a covenant between Jehovah and the king and the people, that they should be Jehovah's people; between the king also and the people.

And Joiada made a covenant between the Lord, and the king, and the people, that they should be the people of the Lord, and between the king and the people.

And Jehoiada made an agreement between the Lord and the king and the people, that they would be the Lord's people; and in the same way between the king and the people.

Then Jehoiada formed a covenant between the Lord, and the king and the people, so that they would be the people of the Lord; and between the king and the people.

A covenant - Rather, "the covenant," which either was already an established part of a coronation (marginal reference "k"), or at least became such afterward.

Jehoiada made a covenant - A general covenant was first made between the Lord, the Supreme King, the king his viceroy, and the people, that they should all be the Lord's people; each being equally bound to live according to the Divine law.
Then, secondly, a particular covenant was made between the king and the people, by which the king was bound to rule according to the laws and constitution of the kingdom, and to watch and live for the safety of the public. And the people were bound on their part, to love, honor, succor, and obey the king. Where these mutual and just agreements are made and maintained, there can be nothing else than prosperity in the Church and the state.

And Jehoiada made a (p) covenant between the LORD and the king and the people, that they should be the LORD'S people; between the (q) king also and the people.
(p) That both the king and the people should maintain the true worship of God and destroy all idolatry.
(q) That he should govern and they obey in the fear of God.

And Jehoiada made a covenant between the Lord and the king and the people, that they should be the Lord's people,.... Renewed the covenant between the Lord on the one part, and the king and the people on the other; assuring them, that as God had declared that he would be their God, he would yet be their God to bless and protect them, they continuing in obedience to him; and obliging them to promise that they would serve the Lord their God, and him only, and root out all idolatry from the land, and restore, and continue in, the pure worship of God:
between the king also and the people; he promising, on his part, that he would govern them according to the law of God, and protect them in their rights and properties, privileges and liberties; and they, on their part, that they would honour and obey him, and be his faithful subjects. In 2-Chronicles 23:16 Jehoiada is said to make this covenant between him, &c. which may be understood of the Lord; or if of himself, the meaning is, that it was made between him, the king and people, and the Lord.

King and people would cleave most firmly to each other, when both had joined themselves to the Lord. It is well with a people, when all the changes that pass over them help to revive, strengthen, and advance the interests of religion among them. Covenants are of use, both to remind us of, and bind us to, the duties already binding on us. They immediately abolished idolatry; and, pursuant to the covenant with one another, they expressed mutual readiness to help each other. The people rejoiced, and Jerusalem was quiet. The way for people to be joyful and at peace, is to engage fully in the service of God; for the voice of joy and thanksgiving is in the dwellings of the righteous, but there is no peace for the wicked.

JEHOIADA RESTORES GOD'S WORSHIP. (2-Kings 11:17-20)
a covenant between the Lord and the king and the people--The covenant with the Lord was a renewal of the national covenant with Israel (Exodus. 19:1-24:18; "to be unto him a people of inheritance," Deuteronomy 4:6; Deuteronomy 27:9). The covenant between the king and the people was the consequence of this, and by it the king bound himself to rule according to the divine law, while the people engaged to submit, to give him allegiance as the Lord's anointed. The immediate fruit of this renewal of the covenant was the destruction of the temple and the slaughter of the priests of Baal (see 2-Kings 10:27); the restoration of the pure worship of God in all its ancient integrity; and the establishment of the young king on the hereditary throne of Judah [2-Kings 11:19].

A covenant - A sacred covenant whereby he solemnly engaged both the king, and people, that they should be the Lord's people; that they should renounce, and root out all idolatry, and set up and maintain God's true worship. Between the king - This was a civil covenant, whereby the king engaged himself to rule them justly, and in the fear of God; and the people obliged themselves to defend and obey him.
