Obey the commands of the Lord and will not neglect the calling of the Lord.

Nehemiah 9:32-10:39
In view of all this, we are making a binding agreement,putting it in writing, and our leaders, our Levites and our priests are affixing their seals to it.
The rest of the people- priests, Levites, gatekeepers, singers, temples servants and all who separated themselves from the neighboring peoples for the sake of the law of God, together with their wives and all their sons and daughter who are able to understand- bind themselves with a curse and an oath to follow the Law of God given through Moses and to obey carefully all the commands, regulations and decrees of the Lord.
The people pledge specifically to keep the law's requirements on 1)marriage, the 2)Sabbath, and 3)taxes, tithes and 4)offerings to support the Temple services priest and Levites.
'We will obey that the Lord our god commands... We will not neglect the house of our God.'
Why?
The review of their history in the great confession produces a longing to signup once again to the covenant- agreement with God, so often broken. Nehemiah the governor, priests, Levites ad leaders sign on behalf of the nation. The covenant is ratified in customary style with a curse and an oath.
Now we don't have to make an oath, but in the promise to obey the commands of the Lord for His Love and Grace endure forever.
How?
I will obey that the Lord our God commands and fear our God.
I will not neglect the needy peoples, I will not neglect the calling from the Lord.
