This text comes from The Poetical Works of Robert Burns, a historical songbook transcribed on Wikisource and reproduced from the pinned revision linked below.
Tho' cruel fate should bid us part,
As far's the pole and line;
Her dear idea round my heart
Should tenderly entwine.
Tho' mountains frown and deserts howl,
And oceans roar between;
Yet, dearer than my deathless soul,
I still would love my Jean.
