Tormenting Cares: Poem by Anna Laetitia Barbauld

Sleep, sleep today, tormenting cares
Of earth and folly born!
Ye shall not dim the light that streams
From this celestial morn.
Tomorrow will be time enough
To feel your harsh control;
Ye shall not violate this day,
The sabbath of my soul.
Sleep, sleep for ever, guilty thoughts!
Let fires of vengeance die;
And, purged from sin, may I behold
A God of purity!
