Howard, I think the translation on the link Helen posted makes a bit more sense
"For the sake of this very morning
As a little baby, a little baby
Was born the root of Jesse
As a little baby;
The Strong one who came from Bosra,
The Lawmaker of old on Sinai,
The Redemption to be had on Calvary
As a little baby, a little Baby,
Suckling the breast of Mary,
As a little Baby."
I'd never heard of Bosra (don't remember that from my bible reading youth). Not sure how singable that version is to fit the accents of the tune
