I am well aware that using a bible to prove the bible is circular logic but in this very particular instance we are trying to clarify the lineage within the context of the bible itself. I am asking does the bible itself spell it out that Heli and Jacob were brothers or 1/2 brothers or you just conveniently assuming that in order to make your explanation work?
Just point out chapter and verse or say you are trying to fill in the inconstencies with your imagination? Because I only see 2 seperate contradictory accounts from my end.
Let's work backwards like Luke does.
Matthew 1:18 ESV
"Now the birth of Jesus Christ took place in this way. When his mother Mary had been
betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit."
Mary is Betrothed to Joseph.
Luke 3:23 ESV
Jesus, when he began his ministry, was about thirty years of age, being the son (
as was supposed) of Joseph, the son of Heli.
The key phrase is "as was supposed" with Joseph being the son of Heli. Joseph is betrothed to marry Heli's daughter, Mary. Joseph bears the name of Heli so his name will not be blotted out of Israel.
Deuteronomy 25:5-6 ESV
5 “
If brothers dwell together, and
one of them dies and has no son, the wife of the dead man shall
not be married outside the family to a stranger. Her husband’s brother shall go in to her and take her as his wife and perform the duty of a husband’s brother to her. 6And the
first son whom she bears shall succeed to the name of his dead brother, that his name may not be blotted out of Israel.
Brothers or Half Brothers, this law still applied to them. When we investigate, we apply critical thinking and so we can answer questions outside of the passage.
I suggest you read the first 5 books of the Old Testament to understand the Law because much of the New Testament will reference the Old Testament with the assumption that the reader will know the reference or at least go and investigate.
