Buy or Sell
The prohibition to buy or sell and conduct business on the Sabbath, though not precisely mentioned in the fourth commandment, is implicit in it. The ban on conducting commerce is without a doubt included in guidelines pertaining to that day.
The fourth commandment
“Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it” (Exodus 20:8-11).
The prophet Nehemiah instructed the people not to conduct merchandise on the Sabbath day in observance to the fourth commandment. For he said, “if the peoples of the land brought wares or any grain to sell on the Sabbath day, we would not buy it from them on the Sabbath …” (Nehemiah 10:31).
And the prophet Amos described the sad spiritual conditions of the land of Israel after the Assyrian captivity. At that time, people broke the Sabbath commandment by selling and buying on the Sabbath. For they said to one another, “When will the New Moon be past, that we may sell grain? And the Sabbath, that we may trade wheat?” (Amos 8:5).
Also, the prophet Isaiah admonished the people not to do unholy work on the Sabbath. He said, “If you turn away your foot from the Sabbath, from doing your pleasure on My holy day, and call the Sabbath a delight, the holy day of the LORD honorable, and shall honor Him, not doing your own ways, nor finding your own pleasure, nor speaking your own words” (Isaiah 58:13). The Sabbath day gives people an opportunity to be unselfish and do things that are pleasing to God (1 John 3:22) and to others.
Likewise, the prophet Jeremiah instructed the people saying, “Thus says the LORD: “Take heed to yourselves, and bear no burden on the Sabbath day, nor bring it in by the gates of Jerusalem; nor carry a burden out of your houses on the Sabbath day, nor do any work, but hallow the Sabbath day, as I commanded your fathers“ (Jeremiah 17:21,22). Such activities that break the Sabbath are rejected by the Lord (Isaiah 56:2–6).
