Nehemiah 9:4 & 5a
"Standing on the stairs of the Levites were Jeshua, Bani, Kadmiel, Shebaniah, Bunni, Sherebiah, Bani and Kenani. They cried out with loud voices to the Lord their God. And the Levites - Jeshua, Kadmiel, Bani, Hashabneiah, Sherebiah, Hodiah, Shebaniah and Pethahiah - said: 'Stand up and praise the Lord your God, who is from everlasting to everlasting.'" NIV translation
We see that this great confession started with the leaders and servants of the Lord. They loudly and openly called on the Lord and urged the people to worship Him. We see that they are listed and are reminded of the fact that God takes note of our service to Him and we will be rewarded for our labor. They begin to worship by acknowledging God as the Creator of all things. This is important as it is the basis for His authority to govern the affairs of men.
