Abdu’l-Baha is the one who has interpreted the reference of the Bab concerning David, by saying that there were two Davids, one of them was the author of the Psalms. The Tablet in which the Master states this is absolutely authentic, but at the moment the original is not available.
He Whom God Will Make Manifest
The Bab said that whenever “He whom God will make manifest” appears, accept Him. He never said don’t accept Him until after the lapse of 1000 years. Also Baha’u’llah says that in the year 9 of the Babi Dispensation the time was ripe for the Revelation of “He whom God will make manifest”. As the Bab was not only a Manifestation but a Herald of this Baha’i Faith, the interval between His Revelation and that of Baha’u’llah was of shorter duration. His Dispensation in a sense will last as long as Baha’u’llah’s lasts.
The Holy Book—The Aqdas
There are no doubtful verses in the Holy Book, the Aqdas. The reason it is not circulated amongst all the Baha’is is, first, because the Cause is not yet ready or sufficiently matured to put all the provisions of the Aqdas into effect and, second, because it is a book which requires to be supplemented by detailed explanations and to be translated into other languages by a competent body of experts. The provisions of the Aqdas are gradually, according to the progress of the Cause, being put into effect already, both in the East and the West.
