Personal favourite is " The song of Hosea" sung to a tune similar to Tom Paxton's "Everytime" and based on the words of the prophet Hosea.
A very moving Hymn not widely known but I will post the words if anyone wants them
Here is the first verse as a taster

How can I forget and leave my loved one
How can I depart my love wounded is my heart
How can I forget that I'm compassion
How can I depart from her nearer to my heart

O Israel why have you pierced my heart why have you gone
see your love is melting like the dew drop
Dry and fallow lies your ground withered is your heart

Don't know who wrote it but has been a longtime favourite
