Origin of Yom Kippur?

[David Dalton]

(I asked this on some Jewish groups as well, but thought
there might be knowledgeable scholars on here as well.)

Did the observance of Yom Kippur originate with Moses,
or does it date to an earlier figure such as Jacob?

Right now the phase of the moon is the same phase as
Yom Kippur though of course it is not the right lunar month.

[Malachi17]

The holiday itself is eternal and was practiced, as far as I know, when
the Temple existed heavily since it was the last day before the doors
were closed. The earthly Temple, however, was based on the heavenly and
existed well before the earthly version.

This article examines the root word of "kafar" as it relates to Yom
Kippur and discusses precedents where it occurs in the Bible:
