Verzage nicht du Häuflein klein. [In Trouble.] Concerning the authorship of this hymn there are three main theories—i. that it is by Gustavus Adolphus; ii. that the ideas are his and the diction that of his chaplain, Dr. Jacob Fabricius; and iii. that it is by Altenburg.
This hymn has ever been a favourite in Germany, was sung in the house of P. J. Spener every Sunday afternoon, and of late years has been greatly used at meetings of the Gustavus Adolphus Union—-an association for the help of Protestant Churches in Roman Catholic countries. In translations it has passed into many English and American collections.
