marriages were preferred to exogamous marriages: Abraham married his half-sister(Gen. 20:12); Isaac married Rebeccah, the granddaughter of Abraham 's brother and niece, his double first cousin once removed (Gen. 24:5); Jacob married Leah and Rachel, who also were his first cousins, the daughters of his mother's brother(Gen. 29:12); and Esau married Mahalat, the daughter of Ishmael , his uncle, also a first cousin (Gen. 28:9). It is quite clear that Abraham wished Isaac to marry someone not a Canaanite; later Esau understood that the daughters of Canaan would not please his father, Isaac. There were many instances which demonstrated that endogamous marriages were preferred for religious, family, and national reasons.
It would be appropriate to look at the Biblical legislation against mixed marriage more closely. A prohibition against marriage with Edomites and Egyptians appeared in Deuteronomy 23:8-9. Children of such unions were not to be admitted into the congregation until the third generation. The Bible reported no marriages with Edomites , but mentioned a number of marriages with Egyptians and two involved problems. Leviticus 24:10-11 dealt with the son of an Israelite woman and an Egyptian father who became a blasphemer. Solomon married many foreign wives for the purpose of political alliance, and among them was a daughter of Pharaoh (I Kings 3:1, 9:16, 11:1). The Book of Kings specifically warned against these foreign wives:"You shall not enter into marriage with them, neither shall they with you, for surely they will turn away your heart after their gods"(I Kings 11:2), which happened in the case of Solomon . Finally, there is a reference to Sheshan who married his daughter to Jarha, an Egyptian slave(I Chronicles 2:34). These three isolated incidents indicate that such marriages involved both male and female Egyptians. Moabites and Ammonites were prohibited from being admitted to the congregation of the Lord... even in the tenth generation"(Deut. 23:4). This statement contains no reference to mixed marriages. Negative references connected with mixed marriages refer to Naamah, the Ammonite wife of Rehoboam (II Chronicles 12:13). Joash was slain by courtiers whose
