30and that we would not give our daughters to the peoples of the land, nor take their daughters for our sons:

31and 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.
