2 Chronicles 29:10-11

It is in my heart to make a covenant with the Lord, &c. To engage by solemn vows and promises to worship him only, and in that way which he hath appointed: for I am sure that his fierce anger will not otherwise be turned away from us. This covenant he would not only make for himself, but bring his people also into the bond of it. My sons So he calls them, though many of them were elder than himself, because he was by his tender love and affection, as he was by his office, obliged to be a nursing father to them. Be not now negligent In sanctifying yourselves and the temple, (2 Chronicles 29:5,) and in quickening and preparing yourselves and the people for God's service.
