"Ishmael,Isaac and Jacob do they come from the same bloodline and offspring or no?
who is Naomi and Ruth out of the O.T. do they belong to this same bloodline?
Issac and Ishmael are brothers through Abraham...he is their father though they have different mothers...Sara was the mother of Isaac and Hagar the mother of Ishmael...that is their bloodline....Sara is said to be the half sister of Abraham....though I am not certain....(which would kind of make it incestuous no?)
Jacob was the son of Issac....
Naomi was the mother in law of Ruth...so they were not blood relation but were related by marriage...but Ruth also married a kinsman of Naomi Boaz whom she beget a son Obed
So what other question?
