1 Kings 8:9
There was nothing in the ark save the two tables of stone, which Moses put there at Horeb, when the LORD made a covenant with the children of Israel, when they came out of the land of Egypt.
There was nothing in the ark, save the two tables of stone which Moses put there at Horeb,.... That is, there were no other writings; or, as Ben Gersom says, no other part of the law, but the decalogue otherwise he observes there were in it Aaron's rod and the pot of manna, according to Hebrews 9:4 though the particle there may be rendered "at", or "with", or "by", See Gill on "Hebrews 9:4" and so they might be not within it, but in some place on the sides of it, see
when the LORD made a covenant with the children of Israel, when they came out of the land of Egypt; about two months after.
