The time for the people to show their sadness came after the Feast of Booths. The people gathered to admit all their sins out loud to God. They did this while they worshipped and praised God.
As they prayed, the Jews remembered God’s work among them. All the stories mentioned in the prayer are recorded in other books of the Bible. They are recorded in the books from Genesis through 2 Chronicles.
The Jews remembered when God told Abraham to move from Babylon to Canaan. They remembered how God had been faithful to them since then. They recognised that God is a gracious God. He had always been so good to them.
They also admitted all the ways that they had been proud and stubborn. Over and over God’s people had said no to him and they had chosen to do evil. They were very sorry about this and they repented. They were suffering. They longed for God to save them from being slaves of the Persian government.
So they once again committed to being faithful to the Mount Sinai covenant. This included men, women and children who were old enough to understand. They all agreed to follow God’s laws. They agreed not to join the families of people who worshipped false gods. They agreed to rest on the Sabbath day. They agreed to give the first share of their crops and a tenth of everything. They would give these to support the Levites and to take care of the temple.
