This text comes from The Poetical Works of Robert Burns, a historical songbook transcribed on Wikisource and reproduced from the pinned revision linked below.
The man, in life wherever plac'd,
Hath happiness in store,
Who walks not in the wicked's way,
Nor learns their guilty lore:
Nor from the seat of scornful pride
Casts forth his eyes abroad,
But with humility and awe
Still walks before his God.
That man shall flourish like the trees
Which by the streamlets grow;
The fruitful top is spread on high,
And firm the root below.
But he whose blossom buds in guilt
Shall to the ground be cast,
And like the rootless stubble tost,
Before the sweeping blast.
For why? that God the good adore
Hath giv'n them peace and rest,
But hath decreed that wicked men
Shall ne'er be truly blest.
