If the wife accompany her husband on a journey, and differences arise between them on the way, he is required to provide her with her expenses for one whole year, and either to return her whence she came or to entrust her, together with the necessaries for her journey, to a dependable person who is to escort her home. Thy Lord, verily, ordaineth as He pleaseth, by virtue of a sovereignty that overshadoweth the peoples of the earth.

Ye are but vassals, O kings of the earth! He Who is the King of Kings hath appeared, arrayed in His most wondrous glory, and is summoning you unto Himself, the Help in Peril, the Self-Subsisting. Take heed lest pride deter you from recognizing the Source of Revelation, lest the things of this world shut you out as by a veil from Him Who is the Creator of heaven. Arise, and serve Him Who is the Desire of all nations, Who hath created you through a word from Him, and ordained you to be, for all time, the emblems of His sovereignty.

By the righteousness of God! It is not Our wish to lay hands on your kingdoms. Our mission is to seize and possess the hearts of men. Upon them the eyes of Bahá are fastened. To this testifieth the Kingdom of Names, could ye but comprehend it. Whoso followeth his Lord will renounce the world and all that is therein; how much greater, then, must be the detachment of Him Who holdeth so august a station! Forsake your palaces, and haste ye to gain admittance into His Kingdom. This, indeed, will profit you both in this world and in the next. To this testifieth the Lord of the realm on high, did ye but know it.

Be watchful lest the concerns and preoccupations of this world prevent you from observing that which hath been enjoined upon you by Him Who is the Mighty, the Faithful. Be ye the embodiments of such steadfastness amidst mankind that ye will not be kept back from God by the doubts of those who disbelieved in Him when He manifested Himself, invested with a mighty sovereignty. Take heed lest ye be prevented by aught that hath been recorded in the Book from hearkening unto this, the Living Book, Who proclaimeth the truth: "Verily, there is no God but Me, the Most Excellent, the All-Praised." Look ye with the eye of equity upon Him Who hath descended from the heaven of Divine will and power, and be not of those who act unjustly.

Beware lest any name debar you from Him Who is the Possessor of all names, or any word shut you out from this Remembrance of God, this Source of Wisdom amongst you. Turn unto God and seek His protection, O concourse of divines, and make not of yourselves a veil between Me and My creatures. Thus doth your Lord admonish you, and command you to be just, lest your works should come to naught and ye yourselves be oblivious of your plight. Shall he who denieth this Cause be able to vindicate the truth of any cause throughout creation? Nay, by Him Who is the Fashioner of the universe! Yet the people are wrapped in a palpable veil. Say: Through this Cause the day-star of testimony hath dawned, and the luminary of proof hath shed its radiance upon all that dwell on earth. Fear God, O men of insight, and be not of those who disbelieve in Me. Take heed lest the word "Prophet" withhold you from this Most Great Announcement, or any reference to "Vicegerency" debar you from the sovereignty of Him Who is the Vicegerent of God, which overshadoweth all the worlds. Every name hath been created by His Word, and every cause is dependent on His irresistible, His mighty and wondrous Cause. Say: This is the Day of God, the Day on which naught shall be mentioned save His own Self, the omnipotent Protector of all worlds. This is the Cause that hath made all your superstitions and idols to tremble.

any reference to Viceregency debar you from the sovereignty of Him Who is the Viceregent of God
The word here translated "Vicegerency" is, in the original Arabic, "vilayát", which has a range of meanings including "vicegerency", "guardianship", "protectorship" and "successorship". It is used in relation to God Himself, to His Manifestation, or to those who are the appointed Successors of a Manifestation.
In this verse of the Aqdas, Bahá’u’lláh warns against allowing such concepts to blind one to the “sovereignty” of the new Divine Manifestation, the true “Vicegerent of God”.
