Famous quotes containing the words windows and/or version:
“In winter we lead a more inward life. Our hearts are warm and cheery, like cottages under drifts, whose windows and doors are half concealed, but from whose chimneys the smoke cheerfully ascends.... We enjoy now, not an Oriental, but a Boreal leisure, around warm stoves and fireplaces, and watch the shadow of motes in the sunbeams.”
—Henry David Thoreau (1817–1862)
“Remember that you were a slave in the land of Egypt, and the LORD your God brought you out from there with a mighty hand and an outstretched arm; therefore the LORD your God commanded you to keep the sabbath day.”
—Bible: Hebrew, Deuteronomy 5:15.
See Exodus 22:8 for a different version of this fourth commandment.
