Nehemiah 9:13

Thou camest down also upon Mount Sinai
By some visible tokens of his presence, as a cloud, fire, smoke which must be understood consistent with his omniscience, see ( Exodus 19:18 ) ,

and spakest with them from heaven;
the decalogue or ten commandments, ( Exodus 20:1-17 ) ,

and gavest them right judgments and true laws, good statutes and
commandments;
both judicial and ceremonial, which were of excellent use to them in their civil and ecclesiastical polity; these were not spoken to Israel, but given to Moses on the mount, to be delivered to them.
