Contrast between the system and priesthood of Moses, and the ministry and priesthood of Christ, are Scripturally and rationally made. Jesus brings a better hope to draw near to God by a better covenant.
King David celebrates the successful arrival of the ark of the covenant to Jerusalem, establishing a system of service for the care of the ark. He also delivers a psalm that he wrote just for this occasion.
The writer takes his audience to a mysterious passage in Genesis that was preserved by God for this very moment and mission. To prepare them to accept a priesthood superior to the one given to them by Moses.
King David again sets out to bring the Ark of the Covenant to Jerusalem and is successful because Scripture concerning transporting the Ark was followed. He sacrifices, dances and fills the city with joy; except for at least one.
In a gentle tone he tells them that better things belong to our salvation. Nudging them forward, encouraging them not to be sluggish, since God is faithful, as Abraham realized. God’s reliability is an anchor of hope.
