Famous quotes containing the word key:
“The safety of the republic being the supreme law, and Texas having offered us the key to the safety of our country from all foreign intrigues and diplomacy, I say accept the key ... and bolt the door at once.”
—Andrew Jackson (1767–1845)
“At the last, tenderly,
From the walls of the powerful fortress’d house,
From the clasp of the knitted locks, from the keep of the well-closed doors,
Let me be wafted.
Let me glide noiselessly forth;
With the key of softness unlock the locks—with a whisper,
Set ope the doors O soul.”
—Walt Whitman (1819–1892)
“I cannot tell what I am as much afraid of, as a woman who invariably washes on Monday. It is a kind of key to character; and if her mouth is not puckered and her brow wrinkled, they will be, unless she repents.”
—Jane Grey Swisshelm (1815–1884)
