31 We will not buy on the Sabbath or on a holy day from the neighboring peoples who bring their wares and all kinds of grain to sell on the Sabbath day. We will let the fields lie fallow every seventh year, and we will cancel every loan.

Darby

31 and that if the peoples of the land brought wares or any grain on the sabbath day to sell, we would not take it of them on the sabbath, or on [any] holy day; and that we would leave [the land uncultivated] the seventh year, and the exaction of every debt.

KJV

31 And [if] the people of the land bring ware or any victuals on the sabbath day to sell, [that] we would not buy it of them on the sabbath, or on the holy day: and [that] we would leave the seventh year, and the exaction of every debt.
