Hebrews 9:3-4

9:3 And after the second curtain there was a tent called the holy of holies. 9:4 It contained the golden altar of incense and the ark of the covenant covered entirely with gold. In this ark ¹  were the golden urn containing the manna, Aaron’s rod that budded, and the stone tablets of the covenant.

¹ tn Grk “in which”; in the translation the referent (the ark) has been specified for clarity.
