These songs are together because they are both set to HEINLEIN (attributed to Martin Herbst).
George H. Smyttan wrote the text for the Lenten Hymn “Forty Days and Forty Nights”. The lyrics and sheet music are at Hymnary.
Alan G. McDougall’s hymn “From the Depths We Cry to You” (text here) is also on a Lenten theme so perhaps the minor key suggests this state of mind.
