Excellent, Guest Q! I should have done a more thorough search in the DT. I was wondering about the last verse above which doesn't end in a rhyme, whether it was inaccurately transcribed:

Fox has a hole in de groun',
De bird has a nes' in de air;
Everything has a hiding place,
But we po' sinners has none. (CHO)

However, the Fenner version doesn't rhyme either (only has a 3-line verse):

De fox hab hole in de groun'
An' de bird hab nest in de air,
But we, poor sinners, hab none.

I'm fond of rhyming for what it's worth and was gratified to see H.T. Burleigh's arrangement:

O, de foxes dey hab holes in de groun',
An' de birds hab nests in de air,
An' ev'ry thing has a hidin' place,
But us po' sinners ain't got nowhere.

This is really fun to explore!

Cheerily,
Charley Noble
