1 Chronicles 6:49-53

Reader! do remark, with what peculiar dignity and honor Aaron is spoken of, in this sacred service of the sacrifice. Singing, no doubt, formed a very interesting part of the temple worship: but nothing compared to the ministry of sacrifices, to which Aaron and his sons were called. As all sacrifices pointed to the One Great Sacrifice: so all the priests typified that One Almighty High priest, the Lord Jesus Christ, whom both the altar, sacrifice, and priest shadowed forth and represented.
