But only three in all God's universe
Have heard this word thou hast said,--Himself, beside
Thee speaking, and me listening ! and replied
One of us . . . that was God, . . . and laid the curse
So darkly on my eyelids, as to amerce
My sight from seeing thee,--that if I had died,
The deathweights, placed there, would have signified
Less absolute exclusion. 'Nay' is worse
From God than from all others, O my friend !
Men could not part us with their worldly jars,
Nor the seas change us, nor the tempests bend;
Our hands would touch for all the mountain-bars:
And, heaven being rolled between us at the end,
We should but vow the faster for the stars.

Elizabeth Barrett Browning
