"Gib unsern" (#68d)

"Verleih uns Freiden gnädiglich" (#68c)

[Edit:  I discovered that I misspelled the title; it's actually "Verleih uns Frieden gnädiglich."]

Next to the title, there's a note that I think says, "In the old melody" ("in alte Melodie"), distinguishing this from #68b.

16', 8', and 4'

"Verleih uns Freiden gnädiglich" (#68b)

[Edit:  I discovered that I misspelled the title; it's actually "Verleih uns Frieden gnädiglich."]

"Erhalt' uns Herr, bey deinem Wort" (#68a)

This is the first of four tunes numbered 68.  Not all of the titles are the same, but the tunes are a bit similar.  Apparently, this is why they're grouped together.
