For ever blessed be the Lord. J. Watts. [Psalms cxliv.] In his Psalms of David, 1719, this version in 3 stanzas of 4 lines forms the first of three CM. hymns on Psalms cxliv., and is accompanied with the following note:—
"The sense of a great part of this Psalm is found often repeated in the Book of Psalms. I have therefore only taken three small parts of it, and form'd three distinct hymns on very different subjects."
Although frequently found in the older collections its modern use is limited.
