The Nuts of Knowledge (1903)
Context: It was the warrior within
Who called 'Awake, prepare for fight:
Yet lose not memory in the din:
Make of thy gentleness thy might:
'Make of thy silence words to shake
The long-enthroned kings of earth:
Make of thy will the force to break
Their towers of wantonness and mirth.

When We Two Parted (1808), st. 4.
Context: In secret we met
In silence I grieve,
That thy heart could forget,
Thy spirit deceive.
If I should meet thee
After long years,
How should I greet thee?
With silence and tears.

"April", in Poems (1859)
Context: Awakener, come!
Fiing wide the gate of an eternal year,
The April of that glad new heavens and earth
Which shall grow out of these, as spring-tide grows
Slow out of winter's breast.
Let Thy wide hand
Gather us all — with none left out (O God!
Leave Thou out none!) from the east and from the west.
Loose Thou our burdens: heal our sicknesses;
Give us one heart, one tongue, one faith, one love.
In Thy great Oneness made complete and strong —
To do Thy work throughout the happy world —
Thy world, All-merciful, Thy perfect world.

1770s, To His Excellency, George Washington (1775)

Be Kind
