Bahá'u'lláh here alludes to 'Abdu'l-Bahá as His Successor and calls upon the believers to turn towards Him. In the Book of the Covenant, His Will and Testament, Bahá'u'lláh discloses the intention of this verse. He states: "The object of this sacred verse is none other except the Most Mighty Branch." The "Most Mighty Branch" is one of the titles conferred by Bahá'u'lláh on 'Abdu'l-Bahá. (See also notes 66 and 184.)
