The Scroll of the Covenant Moses Read at Mount Sinai Is the End of Leviticus
Jubilees, and later the Mekhilta, suggest that the covenant ceremony described after the revelation at Sinai (Exodus 24) actually took place earlier — at the moment when the Israelites declared נַעֲשֶׂה, “we will do” (Exodus 19). According to Rabbi Ishmael, it was then that Moses read Leviticus 25–26 to the people — a section explicitly framed as spoken at Sinai, and which sets out the terms of the covenant.
