Abraham, on Him be peace, made a covenant concerning Moses and gave the glad-tidings of His coming. Moses made a covenant concerning the promised Christ, and announced the good news of His advent to the world. Christ made a covenant concerning the Paraclete and gave the tidings of His coming. The Prophet Muhammad made a covenant concerning the Báb, and the Báb was the One promised by Muhammad, for Muhammad gave the tidings of His coming. The Báb made a Covenant concerning the Blessed Beauty, Bahá'u'lláh, and gave the glad-tidings of His coming for the Blessed Beauty was the One promised by the Báb. Bahá'u'lláh made a covenant concerning a Promised One Who will become manifest after one thousand or thousands of years. That Manifestation is Bahá'u'lláh's Promised One, and will appear after a thousand or thousands of years.
