Nehemiah 10:28-29

The rest of the people took an oath. They were the priests, Levites, gatekeepers, singers, Temple servants, all those who separated themselves from foreigners to keep the Teachings of God, and also their wives and their sons and daughters who could understand. They joined their fellow Israelites and their leading men in taking an oath, which was tied to a curse in case they broke the oath. They promised to follow the Teachings of God, which they had been given through Moses the servant of God, and to obey all the commands, rules, and laws of the LORD our God.
