Exodus 24:3

And Mosheh came and set before the people all the words of the Lord, and all the judgments. And all the people answered with one voice, and said, All that the Lord hath spoken we will do.

AND MOSES CAME AND TOLD THE PEOPLE ALL THE WORDS OF THE ETERNAL. At the time that this whole commandment mentioned here was given, Moses was at the place where he drew near unto the thick darkness where G-d was, and now he came to that “far off” place where the people had been at the time of the Revelation, and told them all that he had been commanded [i.e., beginning with Ye yourselves have seen — above 20:19 — up to the end of all the commandments and ordinances, 23:33], and they listened to his voice. Scripture does not say here: “and he came down from the mountain,” for they were all then at the lower part of the mountain,, 19:17. and not at the top where the Glory of G-d was; [the difference] was only that Moses was near the place of the thick darkness, whilst the people stood from afar at the time of the giving of the commandments, as I have explained., 19:19, and 20:15. When Moses left his place and began coming towards the people, all the heads of their tribes and their elders came up to the place where the priests that come near to the Eternal, 19:22. stood, and said to him, Now therefore why should we die? for this great fire will consume us; Go thou near, and hear etc.,, Verse 24. for they thought that the Revered G-d Himself would tell them all the commandments of the Torah just as He had told them the Ten Commandments. Then Moses came together with the heads of the tribes and the elders to the place where the people were standing and told all of them all the words of G-d, and they said, “We will do all that He has commanded us in the Ten Commandments, and we will hearken to your voice in everything that you have commanded, or will command in His Name, exalted be He.” When Moses went back afterwards to the edge of the mountain with the elders, as G-d had commanded him, then G-d said to him again, Come up to Me into the mountain, and be there. It was at that time that He informed him, I have heard the voice of the words of the people, which they have spoken unto thee; they have well said all that they have spoken, and He commanded him: Go say to them: Return ye to your tents. But as for thee, stand thou here by Me, and I will speak unto thee all the commandment, and the statutes, and the ordinances, which thou shalt teach them., Verses 27-28. It is with reference to this that He said here, And I will give thee the Tablets of stone, and the law and the commandment, meaning, that to you alone I will give the law and the commandments which you will teach them, and they will keep them as they have undertaken to do.

'ויבא משה ויספר לעם את כל דברי ה, the matters Moses told the people were those reported in the Torah between 20,8 and the beginning of chapter 21.
