Nehemiah 10:29-31

29are joining with their kinsmen, their nobles, and are 12taking on themselves a curse and an oath to walk in God’s Law, which was given through Moses, God’s servant, and to keep and to 3comply with all the commandments of 4God our Lord, and His ordinances and statutes; 30and 5that we will not give our daughters to the peoples of the land or take their daughters for our sons. 31As 6for the peoples of the land who bring wares or any grain on the Sabbath day to sell, we will not 7buy from them on the Sabbath or on any holy day; and we will forgo the crops of the 8seventh year and 910every debt.
