Question

And I had put away
My labor and my leisure too,
For His Civility –
What is the purpose of the words “labor” and “leisure”?

Answer 1

These words tell us about the great sacrifices made by the speaker for the sake of living in a civilised society.  The speaker left all the hardwork and daily tasks which kept her busy and active.  The speaker also sacrificed her hobbies and recreation which used to entertain her in free time.   The speaker is leaving these things for him.
