The death of the saints is represented as the taking down of the tabernacle, 2Co 5:1, and the putting it off, 2Pe 1:14. All shall be raised up in the great day, when these vile bodies shall be made like the glorious body of Jesus Christ, and so shall be for ever with the Lord.This is the service of the families of the sons of Merari,....
