וַיִּקַּח֙ סֵ֣פֶר הַבְּרִ֔ית וַיִּקְרָ֖א בְּאָזְנֵ֣י הָעָ֑ם וַיֹּ֣אמְר֔וּ כֹּ֛ל אֲשֶׁר־דִּבֶּ֥ר יְהוָ֖ה נַעֲשֶׂ֥ה וְנִשְׁמָֽע׃
Lalu ia mengambil kitab perjanjian itu dan membacakannya dengan didengar oleh bangsa itu. Mereka berkata: “Segala yang telah diucapkan Yang Mahakekal akan kami lakukan dan akan kami dengarkan.”
Rashi
ספר הברית THE BOOK OF THE COVENANT — the book which we have said contained the part of the Torah from בראשית till the “Giving of the Torah” including the Commandments that were given to them at Marah (Mekhilta; cf. Rashi on v. 4).

ויקח ספר הברית, “He took hold of the Book of the Covenant;” It is well known that the Torah was not written in chronological sequential order. The Mechilta of Rabbi Yishmael, on the 19th chapter of the Book of Exodus, has proven this beyond any question. Among other proofs the author has cited is Leviticus 25,2, where the Torah wrote: ושבתה הארץ, that the soil of the land of Israel is to observe a year of lying fallow, (immediately after the Israelites entering that land) and the Torah proceeds to lists the laws pertaining to the sh’mittah cycles followed by the Jubilee cycles, concluding with 26,46: “these are the statutes and social laws that G-d has given as applying to the Jewish people all of which He had revealed to Moses at Mount Sinai.” The Jewish people heard and accepted all the laws including the blessings and curses applying to those who observed them and those who would disobey them, after which Moses took the remainder of the blood and sprinkled it upon them, as the seal of the covenant. He told the people to listen to detailed instructions of these laws starting on the day following. [In other words, the Jews had already bound themselves to be obedient to the Torah’s laws even though they had not yet been written down. There is considerable discussion about the term ספר הברית, here whether what was already written in there at the time Moses read from it was subsequently written in the Torah out of context or not. According to our author’s interpretation of the Mechilta when the Israelites said their famous: נעשה ונשמע generally understood as their giving G-d a blank cheque, this was not so, they simply expressed the wish to learn the details of what Moses had already read out to them.
