The Sabbath is the day of rest modeled by God in the Bible
Work is a good thing and not a curse. However rest is also good in it's proper proportion.
"Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the Lord your God. On it you shall not do any work, you, or your son, or your daughter, or your male servant, or your female servant, or your livestock, or the sojourner within your gates."
