This is a line from Thomas Hood’s poem The Death Bed (1846):
We watched her breathing through the night
Her breathing soft and low,
As in her breast the wave of life
Kept heaving to and fro.
So silently we seemed to speak,
So slowly moved about,
As we had lent her half our powers
To eke her living out.
Our very hopes belied our fears,
Our fears our hopes belied --
We thought her dying when she slept,
And sleeping when she died.
For when the morn came dim and sad,
And chill with early showers,
Her quiet eyelids closed -- she had
Another morn than ours.
