In this chapter, I show that, contrary to Rabbinical claims about the Oral Torah, Moses wrote down all of the Torah.
1. Many passages throughout the Jewish Bible say that Moses wrote down the Torah. Here are some examples.
Moses wrote down this Teaching [ha-torah - התורה] and gave it to the priests, sons of Levi, who carried the Ark of YHWH's Covenant, and to all the elders of Israel.
And Moses instructed them as follows: Every seventh year, the year set for remission, at the Feast of Booths, when all Israel comes to appear before YHWH your God in the place that He will choose, you shall read [tiqra - תקרא] this Teaching [ha-torah] aloud in the presence of all Israel. Gather the people — men, women, children, and the strangers in your communities — that they may hear and so learn to revere YHWH your God and to observe faithfully every word of this Teaching [divrei ha-torah - דברי התורה]. Their children, too, who have not had the experience, shall hear and learn to revere YHWH your God as long as they live in the land that you are about to cross the Jordan to possess. (Deut. 31:9-13)
This passages says that Moses wrote down the Torah. He commanded that the Torah be read every seventh year in the presence of all the people, so that the people learn to follow this Written Torah. Moses makes no mention of following another Torah, in addition to the one that he wrote down.
When Moses had put down in writing the words of this Teaching [divrei ha-torah] in a book [sefer - ספר] to the very end, Moses charged the Levites who carried the Ark of the Covenant of YHWH, saying: Take this book of Teaching [sefer ha-torah] and place it beside the Ark of the Covenant of YHWH your God, and let it remain there as a witness against you. Well I know how defiant and stiffnecked you are: even now, while I am still alive in your midst, you have been defiant toward YHWH; how much more, then, when I am dead! Gather to me all the elders of your tribes and your officials, that I may speak all these words to them and that I may call heaven and earth to witness against them. For I know that, when I am dead, you will act wickedly and turn away from the path that I enjoined upon you, and that in time to come misfortune will befall you for having done evil in the sight of YHWH and vexed Him by your deeds. (Deut. 31:24-29)
According to this passage, Moses wrote down the Torah in a book that was stored in the Ark of the Covenant.
Now it happened after the death of Moses the servant of YHWH, that YHWH spoke to Joshua the son of Nun, Moses’ servant, saying, ... Only be strong and very courageous, to observe to do according to all the law [ha-torah], which Moses my servant commanded you. Don’t turn from it to the right hand or to the left, that you may have good success wherever you go. This book of the law [sefer ha-torah] shall not depart out of your mouth, but you shall meditate on it day and night, that you may observe to do according to all that is written therein: for then you shall make your way prosperous, and then you shall have good success. (Joshua 1:1-8)
God tells Joshua that "all the Torah" that Moses commanded is contained within the "book of the Torah", and that the Torah should be followed "according to all that is written therein". God also says not to depart from the book of the Torah "to the right hand or to the left". This means, in part, not diminishing or increasing the commandments contained within the book of the Torah. Certainly, the Oral Torah contains multitudes of commandments not found in the Written Torah.
And YHWH said to Moses: Write down these words [ha-devarim - הדברים], for in accordance with these words [ha-devarim] I make a covenant with you and with Israel. And he was there with YHWH forty days and forty nights; he ate no bread and drank no water; and he wrote down on the tablets the terms of the covenant, the Ten Commandments [aseret ha-devarim - עשרת הדברים]. (Exodus 34:27-28)
This particular passage does not say that Moses wrote down all of the Torah. It does say that he wrote down the central part of the Torah, which is all "the terms of the covenant" between God and the Jewish people.
2. Despite all the clear statements that Moses wrote down all of the Torah, the Rabbis insist that when it says that he wrote down the Torah, it is only referring to the Written Torah, and that there was another Torah that was passed down orally. However, the following two passages conclusively show that nothing else besides the Written Torah was passed down from Moses.
Moses and the elders of Israel commanded [itsav - יצו] the people, saying: Observe all the Commandments [ha-mitzvah - המצוה] that I command [mitzvah] upon you this day. As soon as you have crossed the Jordan into the land that YHWH your God is giving you, you shall set up large stones. Coat them with plaster and inscribe upon them all the words of this Teaching [divrei ha-torah]. When you cross over to enter the land that YHWH your God is giving you, a land flowing with milk and honey, as YHWH, the God of your fathers, promised you — upon crossing the Jordan, you shall set up these stones, about which I charge you this day, on Mount Ebal, and coat them with plaster. There, too, you shall build an altar to YHWH your God, an altar of stones. Do not wield an iron tool over them; you must build the altar of YHWH your God of unhewn stones. You shall offer on it burnt offerings to YHWH your God, and you shall sacrifice there offerings of well-being and eat them, rejoicing before YHWH your God. And on those stones you shall inscribe every word of this Teaching [ha-torah] most distinctly. (Deuteronomy 27:1-8)
Moses died before entering the Land. Before his death, he issued an instruction to the people: as soon as the people enter the Land, they are, among other things, to "inscribe ... all the words of this Torah" on large stones. The people, in fact, did obey this instruction.
Then Joshua built an altar to YHWH, the God of Israel, in Mount Ebal, as Moses the servant of YHWH commanded the children of Israel, as it is written in the book of the law of Moses [sefer torat Moshe - ספר תורת משה], an altar of uncut stones, on which no man had lifted up any iron. They offered burnt offerings on it to YHWH, and sacrificed peace offerings. He wrote there on the stones a copy of the law of Moses [mishneh torat Moshe - משנה תורת משה], which he wrote in the presence of the children of Israel. All Israel, and their elders and officers, and their judges, stood on this side of the ark and on that side before the priests the Levites, who carried the ark of YHWH's covenant, the foreigner as well as the native; half of them in front of Mount Gerizim, and half of them in front of Mount Ebal, as Moses the servant of YHWH had commanded at the first, that they should bless the people of Israel. Afterward he read [qara] all the words of the law [ha-torah], the blessing and the curse, according to all that is written in the book of the law [sefer ha-torah]. There was not a word of all that Moses commanded [tsivah - צוה], which Joshua didn't read [qara] before all the assembly of Israel, with the women, the little ones, and the foreigners who were among them. (Joshua 8:30-35)
The passage describes what the people under the leadership of Joshua did when they entered the Land. According to the description, they followed Moses's instruction to the letter. Joshua wrote "on the stones a copy of the Torah of Moses". The book of the Torah of Moses is mentioned a couple of times. Lest we think that, aside from the book, there might have been some other, unwritten, teaching, the passage clearly states: "There was not a word of all that Moses commanded, which Joshua didn't read". Absolutely everything that Moses commanded was read. And since it was read, it must have been written down. And since all of it was written, "not a word of all that Moses commanded" was transmitted in an exclusively oral form, contrary to the claim of the Oral Torah.
3. The Rabbis claim that the word "Law" [torah] refers to the portion of God's Teaching that was written down, while the word "Commandment" [mitzvah] refers to the portion that was not written down, that is, to the Oral Torah. (See the Introduction.) Firstly, there is absolutely no basis to this claim — there is no indication that the mitzvot were not written down. Secondly, the above passages clearly contradict this claim. The passage from Joshua say that everything that Moses commanded was read. Everything must include the mitzvot. Also note that the word "Commandment" [mitzvah] comes from "to command" [tsivah].
Third, the mitzvot are, in fact, written down in the Jewish Bible. Moses says
And this is the Commandment [ha-mitzvah] — the statutes and the rules [ha-chukim v-ha-mishpatim - החקים והמשפטים] — that YHWH your God has commanded [me] to impart to you, to be observed in the land that you are about to cross into and occupy, so that you, your children, and your children's children may revere YHWH your God and follow, as long as you live, all His statutes [chukotayv] and commandments [mitzvotayv] that I enjoin upon you, to the end that you may long endure. Obey, O Israel, willingly and faithfully, that it may go well with you and that you may increase greatly [in] a land flowing with milk and honey, as YHWH, the God of your fathers, spoke to you. (Deut. 6:1-3)
Moses then begins to list the Commandments [mitzvot], right there, in the written text. These commandments include to know that YHWH is God and there is none else (6:4); to love God with all one's being (6:5); to take God's Commandments to heart, to teach them to one's children, to meditate on them, to make them visible in one's actions, to make them the cornerstone of one's household (6:6-9); and so on. Since the mitzvot are listed in the written text, they cannot refer to the Oral Torah, which, according to the Rabbis, is not written in the text.
