Chapter 79 of the Tao Teh Ching talks about the Sage and the Way of Heaven, a covenant, and private affections.

When a great wound is healed,
There will still remain a scar.
Can this be a desirable state of affairs?
Therefore, the Sage, holding the left-hand tally,
Performs his part of the covenant,
But lays no claims upon others.

The virtuous attends to his duties;
The virtueless knows only to levy duties upon the people.
The Way of Heaven has no private affections,
But always accords with the good.
