This is where the genealogy of Matthew ends with Abraham.  Luke continued further back.  He said that Judah was the son of Jacob (τοῦ Ἰακὼβ), who had 12 sons with 4 different women, that become the 12 tribes of Israel.  Jacob was the son of Isaac (τοῦ Ἰσαὰκ), the son of Abraham (τοῦ Ἀβραὰμ), who was the son of Terah (τοῦ Θάρα), the son of Nahor (τοῦ Ναχὼρ).  Throughout the Torah, there was a continual reference to the God of Abraham, Isaac, and Jacob.  These 3 generations were key to Hebrew and Jewish history.  Their stories can be found in the book of Genesis, chapters 12-35.  Remember that Abraham had a son with his wife’s maid, Hagar, who was called Ishmael.  However, both were sent away.  Jacob had a twin brother named Esau, whom he tricked out of his father’s inheritance.  Terah and Nahor can be found in 1 Chronicles, chapter 1:26, and Genesis, chapter 11:24-32.  Nahor was the name of Abram’s grandfather and his brother.  Abram, appeared to be the oldest, took a wife named Sarai, who was barren.  Later it will be revealed that Sarai is his half-sister, since Terah had a concubine.  They all lived at Ur in the Chaldeans, probably in northwest Mesopotamia.  Terah took his son Abram and his wife, Sarai, and his grandson Lot, and left Ur and went to Canaan.  However, they settled in a place that had the same name as his dead son, Haran.  This may have been part of a huge migration in the early second millennium, about 2000 years before the common Christian era.
