Numbers 4:15

15. Covering the sanctuary Since none but Aaron could enter into the holy of holies under the penalty of death, we are to understand, by the sons of Aaron assisting in preparing the sanctuary and its furniture, that the prohibition was in force only when the cloud rested upon the tabernacle. But when this was removed the sons of Aaron might enter the most holy place to assist in these preparations for removal. Now that Christ has rent the veil by his death for us, we may all draw near with boldness, not to the ark of the covenant, divested of the glorious presence of the Shekinah, but to the throne of grace, filled with the presence of the merciful Father, propitiated by the great High Priest, who ever liveth to make intercession for us.
