Have mercy on me, O my God
This versification of Psalm 50 by Father B. Matyuk was adapted into English by Father William Levkulic. This is a good example of a "Lenten hymn" which is not simply a hymn of the Passion, but a hymn of contrition and repentance that would be suitable for singing throughout the Great Fast.
