Jer. xx. 2, LXX.  εἰς τὸν καταῤ& 191·άκτην ὁς ἦν ἐν πύλῃ.  Καταῤ& 191·άκτης τῶν πυλῶν occurs in Dion. Halic. viii. 67, in the same sense as the Latin cataracta (Livy xxvii. 27) a portcullis.  The Vulgate has in nervum, which may either be gyve or gaol.  The Hebrew="stocks", as in A.V. and R.V. καταῤ& 191·άκτης in the text of Basil and the lxx. may be assumed to mean prison, from the notion of the barred grating over the door.  cf. Ducange s.v. cataracta.
