Every thing, and every service, in the Old Testament dispensation, as well as in the gospel Church, points to Christ. Behold, my soul, in the LORD’S appointment of “an altar of earth,” how jealous the LORD is of His honor. If the altar dedicated to the LORD’S service, be of earth, or if it be of stone, there was not to be the least mixture. Nothing hewn, nothing polished by man’s art, or man’s device: “for if,” saith Jehovah “thou lift up thy tool upon it, thou hast polluted it.”
