Hebrews 9:4-6 New Living Translation (NLT)
4 In that room were a gold incense altar and a wooden chest called the Ark of the Covenant, which was covered with gold on all sides. Inside the Ark were a gold jar containing manna, Aaron’s staff that sprouted leaves, and the stone tablets of the covenant. 5 Above the Ark were the cherubim of divine glory, whose wings stretched out over the Ark’s cover, the place of atonement. But we cannot explain these things in detail now.
6 When these things were all in place, the priests regularly entered the first room[a] as they performed their religious duties.
