Sarai (Gen 11-25)

Sarai (Gen 11-25) was born 2089 AC / 2176 BCE Abram @ 10.³ She was the daughter of Terah (Gen 11).² Sarai (Gen 11-25) married Abram (אַבְרָם) (Genesis), son of Terah (Gen 11). Sarai (Gen 11-25) died 2216 AC / 2029 BCE in Kiriath Arba, Canaan, @ 127. She was buried in the Field of Ephron the Hittite.
She became the mother of Isaac (יִצְחָק) (Gen 21-35) 2179 AC / 2066 BCE; Abram @ 100.⁴ In Gen 20:12 Abram claims that Sarai is his half sister, same father different mother. The evidence is that she is not. In Gen 11:31 it tells that Terah and (among others) his daughter-in-law Sarai, the wife of his son Abram set out for Ur. If Sarai were his daughter as Abram claimed then this would have described her as such. I beleive that Abram is lying in Gen 20:12 to cover up his deception on introducing Sarai as his sister, and not his wife. It is also worth noting that in Egypt when he did the same thing he did not make this claim.
