"Jesus loves you more than you will know, woe, woe, woe."

Now, you're right, you and I know the line is "whoa, whoa, whoa"

Interesting. I always thought it wasn't another word at all,
just a repetition of the final syllable for rhythm-maintaining purposes.

"know, -ow,-ow,-ow", pronounced "oh, oh, oh."

More fool me. Live and learn.
