Psalms 40:14

So be it. Chaldean, "Amen." This word, at the beginning of a discourse, implies an affirmative oath; (Matthew vi. 13.) and at the end, it is a mark of approbation, Numbers v. 22. --- Here the Jews terminate the first book of the psalms, which they divide into five. (Calmet) --- St. Jerome rejects this division, as our Saviour mentions only the psalms, and the last psalm has no such conclusion. (Worthington) --- It has Alleluia. All the rest have Amen. See Psalms lxxii., lxxxix., and cvi. (Hebrew) (Berthier) --- The observations which have been made in this first part, will serve to explain many other passages, on which we shall therefore be shorter, as well as in specifying the variations from the original, which are for the most part only apparent, as the intelligent reader may be convinced, by the preceding remarks.
