Baruch iii. 35.  The quoting of Baruch under the name of Jeremiah has been explained by the fact that in the LXX. Baruch was placed with the Lamentations, and was regarded in the early Church as of equal authority with Jeremiah.  It was commonly so quoted, e.g. by Irenæus, Clemens Alexandrinus, and Tertullian.  So Theodoret, Dial. i. (in this edition, p. 165, where cf. note).
