The Boston Camerata's CD is HERE, with sound clips. Vocal "Greenfiels" in German & Englsih is also included. I'll check the Songs of the West version later if no one does (I have the book but it is not in front of me at present).

GREENFIELDS

Da Joseph sein' Brüder ansah,
In Hungersnoth stehen allhie
Sein Herz mit erbarmen war da,
Er fühlte, er weinte für sie;
Er stellte im Unfang sich fremd,
Erkenntlich zu machen ihr' Schuld
Und da sie nun waren beschämt,
erzeigt er sich freundlich voll Huld.

When Joseph his brethren beheld,
Afflicted and tremblng with fear,
His heart with compassion was filled,
From weeping he could not forbear;
A while his behavior was rough,
To bring their past sin to their mind;
But when they were humbled enough,
He hasted to show himself kind.
