Deuteronomy 5:1

And Moses called all Israel
The heads of the various tribes, and elders of the people, as he had on occasion been used to do; unless it can be thought that at different times he repeated the following laws to separate parties and bodies of them, until they had all heard them:

and said unto them, hear, O Israel, the statutes and judgments which I
speak in your ears this day;
the laws, moral, ceremonial, and judicial, which he was about to repeat, and afresh declare unto them, being what they had all a concern in, and under obligation to regard.
