The Priestly source is perhaps the most widely recognized of the sources underlying the Torah, both stylistically and theologically distinct from other material in it. It is considered by most scholars as the latest of all sources, and "meant to be a kind of redactional layer to hold the entirety of the Pentateuch together," it includes a set of claims that are contradicted by non-Priestly passages and therefore uniquely characteristic: no sacrifice before the institution is ordained by Yahweh (God) at Sinai, the exalted status of Aaron and the priesthood, and the use of the divine title El Shaddai before God reveals his name to Moses, to name a few.
