Hebrews 9:3-5

3and behind the second veil, the part of the tabernacle which is called the Holiest of All,

4which had the golden censer and the ark of the covenant overlaid on all sides with gold, in which were the golden pot that had the manna, Aaron’s rod that budded, and the tablets of the covenant;

5and above it were the cherubim of glory overshadowing the mercy seat. Of these things we cannot now speak in detail.
