Just to generally toss on the table:
Were Abraham's progeny via Keturah, ancestrally intact Hebrews? In Genesis 25:1, 2, 3, 4, in v. 2 we find Keturah's son, Shuah.
Since Shuah was a Canaanite (Genesis 38:1, 2), and his daughter was a Canaanitess (1Chronicles 2:3 KJV), doesn't that make Abraham's wife Keturah a Canaanitess?
Since Keturah's son Shuah was a Canaanite (Genesis 38:1, 2), and his daughter, wife of Judah, was a Canaanitess (1Chronicles 2:3 KJV), does that make Judah's son Shelah an ancestrally intact Israelite? Genesis 38:6, 7, 8, 9, 10, 26. Was Shelah an ancestrally intact Jew?
Think about Deuteronomy 7:1, 2, 3, and Ezra 9:1, 2, 7 some 1,400 years later. I don't think those laws were ever divided, rather rescinded, speaking of rightly dividing the Word.
Please listen again to Revelation 2:9 KJV, Revelation 3:9 KJV speaking of rightly dividing the Word: who is a true Jew, and who is a liar Jew?
