having the golden altar of incense and the ark of the covenant covered entirely with gold. This contained a golden jar which held the manna, and the rod of Aaron that sprouted, and the [two stone] tablets of the covenant [inscribed with the Ten Commandments];

Every priest stands [at his altar of service] ministering daily, offering the same sacrifices over and over, which are never able to strip away sins [that envelop and cover us];

We have an altar from which those who serve the tabernacle (sacred tent) have no right to eat.
