Famous quotes containing the word plants:
“So neither the one who plants nor the one who waters is anything, but only God who gives the growth. The one who plants and the one who waters have a common purpose, and each will receive wages according to the labor of each. For we are God’s servants, working together; you are God’s field, God’s building.”
—Bible: New Testament, 1 Corinthians 3:7-9.
“All plants move, but they don’t usually pull themselves out of the ground and chase you.”
—Philip Yordan (b. 1913)
“And time brings down what is both strong and tall.
But plants new set to be eradicate,
And buds new blown, to have so short a date,
Is by his hand alone that guides nature and fate.”
—Anne Bradstreet (c. 1612–1672)
