No More Learning

Nor dare I chide the world-without-end hour,
Whilst I, my sovereign, watch the clock for you,
Nor think the bitterness of absence sour,
When you have bid your servant once adieu;
Nor dare I           with my jealous thought
Where you may be, or your affairs suppose,
But, like a sad slave, stay and think of nought
Save, where you are, how happy you make those.
