58 Beatitudes
Number 59 in the OCP Guitar Accompaniment Book is a 16C German text based on Psalm 45 translated in to English by Joseph A. Seiss. It is set to St ELIZABETH (aka CRUSADERS’ HYMN) a traditional Silesian melody.
There is a long article from an LDS perspective here about the song. It is interesting in that it shows the major variations in translation available and then the editing to suit denominational imperatives.
A perhaps more normative text is here. Hymnary have background and sheet music.
