Exodus 24:1

This was said prior to the event of the 10 comandments, and on 4 Sivan he was told to go up

And Michael, the Prince of Wisdom, said to Mosheh on the seventh day of the month, Come up before the Lord, thou and Aharon, Nadab and Abihu, and seventy of the elders of Israel, and worship at a distance.

AND UNTO MOSES HE SAID: ‘COME UP UNTO THE ETERNAL etc.’ “This section was told to Moses before the giving of the Ten Commandments, on the fourth day of Sivan.” This is Rashi’s language. “And the Eternal said unto Moses: ‘Come up to Me into the mountain, and be there’ — this was said to Moses after the Giving of the Torah.” These too are Rashi’s words. But if so, the sections of the Torah are not in chronological order, nor even in their ordinary sense! Moreover, it is written here, And Moses came and told the people all the words of the Eternal, and all the ordinances, which are these ordinances written above, concerning which He said, And these are the ordinances which thou shalt set before them. For it is not correct to interpret the expression: and all the ordinances, to mean [as Rashi wrote], the ordinances which “the sons of Noah” were commanded, or the laws which were given to the Israelites in Marah which they had already heard and knew, and besides, the word vayesapeir (and he told) always indicates new things which one tells!
But Rabbi Abraham ibn Ezra has already grasped this subject correctly, in explaining the verses to be in their proper order, when he commented: “Up to here is the Book of the Covenant.” On the basis of this statement it can be seen that all the sections of the Torah are in methodical arrangement. For after the Giving of the Torah immediately on the same day G-d said to Moses, Thus shall you tell the children of Israel: Ye yourselves have seen that I have talked with you from heaven, and He began to warn them again against idolatry, by saying, Ye shall not make with Me etc.,, Verse 20. and He continued to command him, Now these are the ordinances which thou shalt set before them, and all the commandments following that, and finally He finished with the admonition against the worship of idols which they find in the Land, and against making a covenant with their worshippers. He then said to Moses, “After you have commanded them this, come up unto the Eternal, thou and Aaron.” The section mentions that Moses did according to the command of G-d, and came to the camp and told the people all the words of the Eternal as He had commanded him, Thus shall you tell the children of Israel: Ye yourselves have seen etc.; and all the ordinances, as He had commanded him, Now these are the ordinances which thou shalt set before them. The people …

ואל משה אמר, from Exodus 20,18 ומשה נגש אל הערפל including the paragraph which the Torah introduces here, all this was communicated to Moses on the same day the Ten Commandments were spoken by G’d. When the Torah here refers to what G’d “had said to Moses,” this refers to what He said to him alone before Moses descended from the mountain on that same day.

'עלה אל ה, this command was issued on the day following Moses’ most recent return from the mountain. He was now bidden to ascend the mountain again of the following day.

אתה ואהרן; immediately after being told this Moses descended. ויספר לעם את כל דברי ה' וגו'. A reference to Exodus 20, 20-21. On the morrow he built an altar, offered sacrifices, and still on the same day he ascended to where the cloud enveloped him for the duration of 6 days (verse 15).

ואל משה אמר, an angel told Moses,

'עלה אל ה; seeing the command did not conclude with the word אלי, “to Me,” we must assume that it was issued by an angel speaking in G’d’s name. On the other hand, in verse 12 where G’d Himself invites Moses, He does add the word אלי, “to Me.”

ואל משה אמר עלה!, after He had finished telling him כה תאמר אל בני ישראל אתם ראיתם in 20,18. At that time He had explained to the people that they must not try and “reach” Him through intermediaries, but that all that was required was an altar made of earth, coupled with the meticulous observance of His commandments as spelled out in the Ten Commandments. The verse tells us that all of these things were explained to the whole nation. However, ואל משה אמר, to Moses himself G’d had said that he should come up to the mountain just as he had been commanded to do already before the revelation, when G’d had said to him in 19,14 לך רד ועלית אתה ואהרן עמך.
