“If the peoples of the land bring in merchandise or any grain on the Sabbath day to sell, we will not buy from them on the Sabbath or on a holy day. We will forego the crops of the seventh year and the exaction of every debt.”
They would do no business on the Sabbath. They would keep holy the Sabbath, which was Saturday. They would not buy from the peoples of the land any grain or merchandise on the Sabbath or holy days. They would forgo crops on the 7th year, the Sabbath year. Finally, they would forgive debts. This was based on Leviticus, chapter 25. This was the beginning of the new Sabbath day regulations.
