Tuesday evening marks the start of Shavuot—the second of the Torah’s pilgrimage festivals—commemorating the divine revelation at Mt. Sinai and the giving of the Torah. Not surprisingly, the Torah reading for the day is the text of the Decalogue, more commonly known as “the Ten Commandments”. It is well-known that the Decalogue text actually appears in two places in the Torah: Exodus 20:1-14, and Deuteronomy 5:6-18. The latter is in the final book of the Torah, written from the perspective of Moses. The two texts are nearly identical, with the only major difference being the description of the Shabbat commandment. In Exodus, we are told to remember (zachor) the Sabbath, while in Deuteronomy we are told to observe or safeguard it (shamor). The former explains Shabbat being in commemoration of God’s creation of the universe, while the latter ties it to God bringing the Israelites out of Egyptian slavery.
If we have two different Decalogue texts, which one was it that the Israelites heard at Sinai? Some say they heard both simultaneously. (Every Friday night in Lecha Dodi we sing shamor v’zachor b’dibbur echad, “‘safeguard’ and ‘remember’ in one utterance…”) Others say the Israelites heard the Exodus version, and the Deuteronomy version is simply Moses’ recollection forty years later, or that Moses purposefully made slight changes to better reflect the needs of the Israelites at the time.
Whatever the case, few are aware that there is actually a third Decalogue text in the Torah! This one is in Exodus 34. Here, we are given a very different set of Ten Commandments:
 You shall make no molten gods.  The feast of unleavened bread shall you keep. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month of spring, for in the month of spring you came out of Egypt.  All firstborn are Mine; and of all your cattle you shall sanctify the males, the firstlings of ox and sheep. And the firstling of a donkey you shall redeem with a lamb; and if you will not redeem it, then you shall break its neck. All the firstborn of your sons you shall redeem. And none shall appear before Me empty.  Six days you shall work, and on the seventh day you shall rest; in plowing time and in harvest you shall rest.  And you shall observe the feast of weeks, even of the first-fruits of wheat harvest,  and the feast of ingathering at the turn of the year. Three times in the year shall all your males appear before Hashem, the God of Israel. For I will cast out nations before you, and enlarge your borders; neither shall any man covet your land when you go up to appear before Hashem, your God, three times in the year.  You shall not offer the blood of My sacrifice with leavened bread;  neither shall the sacrifice of the feast of the Passover be left unto the morning.  The choicest first-fruits of your land you shall bring unto the house of Hashem, your God.  You shall not cook a kid in its mother’s milk.
Aside from idolatry and Shabbat, the above text is a totally different Decalogue! And just in case you thought that this was an unrelated set of ten laws, the Torah continues by emphasizing in the following two verses (Exodus 34:27-28):
And Hashem said unto Moses: “Write these words, for according to these words I have made a covenant with you and with Israel.” And he was there with Hashem forty days and forty nights; he did not eat bread, nor drink water. And he wrote upon the tablets the words of the covenant, the Ten Commandments.
The Torah makes it explicitly clear that these ten are the Ten Commandments that Moses wrote upon the Tablets, and with these ten did God seal the covenant with Israel! What’s going on?
The Golden Calf
The key to solving this mystery is understanding when the second Decalogue was given. This set came after the Israelites worshipped the Golden Calf. That one monumental incident totally changed the course of history. The Arizal explains how the Israelites had affected many tikkunim (spiritual rectifications) during their long years of slavery in Egypt. The Ten Plagues and the Splitting of the Sea accomplished even more rectifications. The preparatory period leading up to the Sinai Revelation ascended the Israelites even further, and when they witnessed God’s Revelation, they had climbed all the way up to the highest level, nearly repairing the entire cosmos. All that was left was to receive the Ten Commandments (the Decalogue which they had heard). This Decalogue was the whole Torah. Once they would have received it and wholeheartedly accepted it, that would have completed the entire rectification of all of Creation, and it would have ushered in the Messianic Age (Moses being Mashiach). Unfortunately, the people worshipped the Golden Calf which, the Arizal explains, now shattered the cosmos once more. Everything reverted to the way it was before the Exodus.
The Sages teach that before the Golden Calf incident, every firstborn male was meant to be a priest. After the Calf, the Levites became the designated priests (since they were the only tribe to abstain from the idolatrous act), and among them, only the descendants of Aaron could serve as high priests. Meanwhile, the Rambam writes that God never wanted the Israelites to bring any sacrifices or offerings (Moreh Nevuchim, III, 32). It seems that this only became necessary after the Golden Calf incident. The Rambam explains that the Israelites could not separate themselves from the old pagan ways they were accustomed to. Offering sacrifices is what they knew; this was their way to connect to a higher power. So, God reluctantly gave them various sacrificial rituals, but only to wean them off this unnecessary practice. The Rambam bases his argument on the words of several prophets, including Jeremiah 7:22, which explicitly has God stating that He never commanded any sacrifices! A careful reading of this verse in Jeremiah shows that God said He never wanted sacrifices when He took the Israelites out of Egypt. Later, however, they became necessary, though only as a temporary measure.
And so, after the Golden Calf incident, God gave Moses a new Decalogue. He affirmed that it was with this new Decalogue that He was forging a covenant with Israel. Reading through these commandments, we see how they are all related to the Golden Calf incident.
The first one commands not creating molten gods. The phrasing here uses the exact same words that were used to describe the Golden Calf. The second commands observing the Passover holiday. Recall that at the Golden Calf incident, the people declared that it was the Calf that took them out of Egypt. Now, the second commandment makes clear that God took them out of Egypt. (This also explains why Moses modified the text of the original Ten Commandments in Deuteronomy, changing it from remembering Creation, to remembering coming out of Egypt.)
The third commandment is to redeem the firstborn males. As we saw above, before the Golden Calf, all firstborn were priests; after, only the Levites and their descendants. Thus, each firstborn now had to be “redeemed”, since they would not be serving as priests. The fourth commandment is the only one to stay the same: keeping the Sabbath.
The fifth and sixth are celebrating Shavuot and Sukkot, the remaining two of three pilgrimage festivals (along with Passover, which was the second commandment). The seventh command introduces sacrifices, and the eighth deals with the Paschal offering. The ninth is about bringing first fruits, another type of offering. All of these fit under the Rambam’s explanation of God giving the Israelites something they were familiar with, since pilgrimage festivals and sacrificial offerings were the two major staples of pagan religion at the time.
The final commandment is not cooking a kid in its mother’s milk, or the prohibition of consuming a mixture of meat and dairy foods. There are many explanations for this enigmatic mitzvah. One of the mystical explanations is once again tied to the Golden Calf incident. It is said that the incident occurred just six hours before Moses returned from Sinai. The nation had only to wait several more hours to avoid the catastrophe. Therefore, waiting six hours to consume dairy after eating meat is seen as a spiritual rectification for that bit of impatience.
Restoring the Ten Commandments
The words of the original Decalogue of Exodus 20 have precisely 620 letters. This is famously said to parallel the 620 commandments in Judaism, 613 being derived from the Torah, and an additional seven that were instituted by the Sages. All of the mitzvot were included in the original Ten Commandments. The entire Torah could be found inscribed on the first set of Two Tablets through those 620 letters. From a mystical perspective, these Ten Commandments were all that was necessary. The 610 commandments that followed only came as a result of the Golden Calf incident, and the need to repair the cosmos from the beginning.
For over three millennia, we have slowly been fulfilling the tikkunim once more. The events that surround Mashiach’s coming are the final steps of that process. Mashiach will come and usher in the grand finale. The Tanakh tells us that he will then establish a new covenant (Jeremiah 31:30-31):
Behold, days are coming, said Hashem, that I will make a new covenant with the house of Israel, and with the house of Judah; not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt…
The Midrash (Yalkut Shimoni, Isaiah 429) says Mashiach will bring a “new Torah”, and the current Torah will be “vain” compared to the Torah of Mashiach (Kohelet Rabbah 11:12). Midrash Tehillim 146:4 is even more specific, suggesting that all non-kosher animals will become kosher, and intimacy with a woman still in the state of niddah will be permitted. A better-known midrash teaches that all of the Torah’s holidays will be abolished (with only Purim—which is not a Torah holiday—remaining).
So, which commandments will be left? The original ten of the first Decalogue; the one that was intended for a Messianic Age to begin with. A simpler set of laws for all of mankind, in an era when (Zechariah 14:9) “Hashem will be king over all of the earth; in that day, God will be One, and His Name will be One.”
