11:17 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.
11:17 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.
11:17-21 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.
