Nehemiah 10:29-31

29They joined their relatives, the nobles, in binding themselves with a curse and an oath to follow God’s teachings given by Moses, God’s servant. They also bound themselves to follow all the commandments, rules, and regulations of the Lord our Lord.

30We will not allow our daughters to marry the inhabitants of the land or allow their daughters to marry our sons.

31If the inhabitants of the land bring merchandise or grain to sell on the day of rest—a holy day, we won’t buy anything from them on the day of rest or any other holy day. During the seventh year, we won’t plant the fields or collect any debts.
