Did ye come here tae drink the wine?
Did ye come here tae borrow?
Or did ye come tae wield yer brand
On the dowie dens o' Yarrow?

I am not come tae drink the wine
Nor yet to beg or borrow
But I am come tae wield my brand
On the dowie dens o' Yarrow!

This particular two verses I have taken from The Dowie Dens Of Yarrow
Janet Russell, on Fyre & Sworde, Songs of the Border Reivers, Fellside FECD131, 1998. The set is similar to Child J.

1. How to translate "beg or borrow" in this context?
2. wield the brand: I intend to swing the sword. Correct?

Thanks. R
