Rashi on Mishpatim 24:3

English: ויבא משה ויספר לעם AND MOSES CAME AND RELATED TO THE PEOPLE — on that same day (the 4th of Sivan). את כל דברי ה׳ ALL THE WORDS OF THE LORD — the commands concerning their keeping apart from women and the setting of bounds at Mount Sinai. ואת כל המשפטים AND ALL THE JUDGMENTS which had been ordained before the Sinaitic legislation: the seven commands given to the “Sons of Noah” (the non-Israelite world), the law of the Sabbath, of filial respect, of the “red heifer” and regarding the administration of justice, all of which had been given to them already in Marah (cf. Sanhedrin 56b).
