In the early days, when the Divine verses were revealed, absolutely no regard was given to the grammatical conventions of the people, whereas in these days, out of considerations of wisdom, regard is being paid to them. If, therefore, a previously revealed Tablet is read out before Our countenance, new wording is, in certain places, revealed to take the place of the old. Such modifications, however, concern only the outward aspects of the wording, for in reality it is correct in the form in which it was originally revealed.

—Bahá’u’lláh
