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