John Gill Commentary Exodus 34:32

"And afterward all the children of Israel came nigh: and he gave them in commandment all that Jehovah had spoken with him in mount Sinai." — Exodus 34:32 (ASV)

And afterward all the children of Israel came nigh
That is, after Aaron and the rulers had had a conversation with Moses, then the whole body of the people by turns were admitted to come before him, and hear the laws of God from him:

and he gave them in commandment all that the Lord had spoken with
him on Mount Sinai ;
besides the two tables of stone, and the testimony written on them, he gave them all the other commands he was ordered to write in a book, and which are recorded in this chapter; he kept back nothing from them, but enjoined them to keep all the Lord had commanded.
