Mt 1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham.Baha'u'llah did not come from Ishmael. Why do you keep saying that, just so you can rule Him out as being the Messiah? It won't work, because Baha'u'llah is descended from David and He sat on the throne of David.
Hopefully, I will only have to post this one more time.
1559. Bahá’u’lláh was a Descendent of Abraham Through Both Katurah and Sarah—Jesse, Son of Sarah, was the Father of David and Ancestor of Bahá’u’lláh
"Regarding your question concerning the Jesse from whom Bahá’u’lláh is descended: The Master says in 'Some Answered Questions', referring to Isaiah, chapter 11, verses 1 to 10, that these verses apply 'Word for word to Bahá’u’lláh'. He then identifies this Jesse as the father of David in the following words: '…for Joseph was of the descendants of Jesse the father of David…', thus identifying the Jesse of Isaiah, chapter 11, with being the father of David. Bahá’u’lláh is thus the descendant of Jesse, the father of David.
"The Guardian hopes that this will clarify the matter for you. It is a tremendous and fascinating theme, Bahá’u’lláh's connection with the Faith of Judaism, and one which possesses great interest to Jew and Christian alike." (From a letter written on behalf of Shoghi Effendi to an individual believer, July 11, 1942)
