Nehemiah 10:29-31

American Standard 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 Jehovah our Lord, and his ordinances and his statutes; ³⁰ and that we would not give our daughters unto the peoples of the land, nor take their daughters for our sons; ³¹ and if the peoples of the land bring wares or any grain on the sabbath day to sell, that we would not buy of them on the sabbath, or on a holy day; and that we would forego the seventh year, and the exaction of every debt.
