Nehemiah 10:29-31

New Revised Standard Version, Anglicised Catholic Edition

²⁹ join with their kin, their nobles, and enter into a curse and an oath to walk in God’s law, which was given by Moses the servant of God, and to observe and do all the commandments of the Lord our Lord and his ordinances and his statutes. ³⁰ We will not give our daughters to the peoples of the land or take their daughters for our sons; ³¹ and if the peoples of the land bring in merchandise or any grain on the sabbath day to sell, we will not buy it from them on the sabbath or on a holy day; and we will forego the crops of the seventh year and the exaction of every debt.
