And to the angel of the church in Philadelphia write; These things said he that is holy, he that is true, he that has the key of David…
The reference here is to Isaiah 22:22: "The key of the house of David will I lay upon his shoulder." This was said of Eliakim, who was thus set up as a type of a greater than himself — a greater than David. Eliakim was royal chamberlain, keeper of the house, like Joseph in Pharaoh's palace. So Christ is represented as not only being the royal possessor of the house, but He also to whom the keeping of its gate was entrusted.
I. THE KEY OF DAVID'S HOUSE. The palace is His, and He keeps the key of it, as the Father has given it to Him. He opens and shuts according as He will.
II. THE KEY OF DAVID'S CASTLE. Besides his palace David had a fort on Zion, which he took from the Jebusites — a stronghold against the enemy. So has our David a strong tower and fortress, into which we run and are safe.
III. THE KEY OF DAVID'S CITY. Yes, the key of Jerusalem, both the earthly and the heavenly.
IV. THE KEY OF DAVID'S TREASURE-HOUSE. That storehouse contains all we need. The unsearchable riches are here.
V. THE KEY OF DAVID'S BANQUETING-HOUSE.
(H. Bonar, D. D.)
