Yahwists code
sometimes refer to Yahwism as “Israelism” and to themselves as “True Israelites.”
Anyone who calls God by a name other than “Yahweh” (such as “God”) or who accepts the oral tradition of the Jews is not a True Israelite and has bought into a false religion.
According to Yahwism, Christianity and most versions of Judaism are false religions.
Priestly code,
is one of the four original sources of the Pentateuch (the first five books of the Old Testament).
The priestly writings are so named because they emphasize the priestly tradition or interest, giving detailed explanations and descriptions of ritual laws and procedures.
Yahweh declares that he himself did reveal himself and his name from the earliest generation of mankind onward AND Yahweh asserts that he did not reveal himself nor his name until Moses at Sinai.
Elohista code
name given by the critics to the presumed author of the earlier part of the Pentateuch whose work in it they allege is distinguished by the use of the word Elohim for God he is to be distinguished from the Jehovist the presumed author of the later portions from his use on the other hand of the word Jehovah for God.
“Deuteronomist code”
The editing and rewriting of the book of Deuteronomy ended sometime in the 5th century BC and most likely in Babylon where many of the royal aristocracy, scribes, and priests lived during and even after the exile of 587 BC.
There, the Deuteronomic scribes reworked the traditions that were handed down to them and updated them to reflect their current exilic condition and to express their hopes of returning to the land.
