This is what I hear:

(verse 6):
Our Saviour must rejine.
(That is how I hear it too. I think "rejine" is fine, to imitate the pronounciation.)

(verse 7):
She made the bed in the back-a-most room
[...]
Upon the top a golden spread
(I hear "golden" too.)

(verse 8):
Rise up, rise up, said she
(That is what I hear, too.)

(verse 9):
[...]
[...]
And thy sweet tears, my mother dear
[...]


Hope this helps.
