Lamb of God
First and second Chronicles are considered the last book of the Jewish Bible, the Talmud.
The predominate view within the writing of Genesis through First and Second Kings is third person, even in his Deuteronomy Narrative, Moses, speaks in third person.
Here in Chronicles we see evidence of a singular author speaking in the first person.
It is believed that this would have been one of the priests, giving an account which should fill in any gaps within the recording of First and Second Kings.
This priest hereby reveals his understanding of the bloodline flowing through Judah which would produce the lamb of God.
