Nehemiah 10:29-31

King James Version

²⁹ They clave to their brethren, their nobles, and entered into a curse, and into 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 judgments and his statutes;

³⁰ And that we would not give our daughters unto the people of the land, not take their daughters for our sons:

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.
