Famous quotes containing the words soft and/or sheaves:
“What did you go out into the wilderness to look at? A reed shaken by the wind? What then did you go out to see? Someone dressed in soft robes? Look, those who wear soft robes are in royal palaces. What then did you go out to see? A prophet? Yes, I tell you, and more than a prophet.”

“Being young you have not known
The fool’s triumph, nor yet
Love lost as soon as won,
Nor the best labourer dead
And all the sheaves to bind.”
