Nehemiah 10:28-29

All of us, including priests, Levites, temple guards, singers, temple workers and leaders, together with our wives and children, have separated ourselves from the foreigners in this land and now enter into an agreement with a complete understanding of what we are doing. And so, we now place ourselves under the curse of the LORD our God, if we fail to obey his laws and teachings that were given to us by his servant Moses.
