yes, maybe that’s why Iraqis are antagonistic towards Israel — since they would have some part blood from the 10 lost tribes, so kind of a fraternal jealousy
The descendants of Ishmael son of Abraham would be DNA connected to all twelve tribes of Israel. The 'law' was the first born son would receive a 'double' blessing, now that would cause jealousy in any family if someone other than the 'first born' received the double blessing.
Say like Jacob/Israel and Esau. They were twins, yet Esau was born first and he sold his birthright for a bowl of *RED* pottage (Genesis 25:29-34) and then Jacob/Israel received the blessing (Genesis 27:27-29)..
It reads... 27 And he came near, and kissed him: and he smelled the smell of his raiment, and blessed him, and said, "See, the smell of my son is as the smell of a field which the LORD hath blessed:
28 Therefore God give thee of the dew of heaven, and the fatness of the earth, and plenty of corn and wine:
29 Let people serve thee, and nations bow down to thee: be lord over thy brethren, and let thy mother's sons bow down to thee; cursed be every on that curseth thee, and blessed be he that blesseth thee.
Interesting to look at this world today and analyze how this would be view in today's world.
