John Trapp on Nehemiah 9:4

Verſe 4. Then ſtood up] Each of theſe eight in his turn, or each in his own proper place: the people being, for more conveniency-ſake, divided into eight ſeveral Congregations.

And cried with a loud voyce] Verbis non modò diſertis, ſed & exſertis, that God might hear (which yet he can do very well without any audible voice, Exod. 14.15. 1 Kings 22.32.) and all the people might hear, and joyn in prayer.

Ʋnto the Lord their God] As being in Covenant with them. This ſhewes their faith, as the former their fervencie. Faith is the foundation of Prayer: and Prayer is the fervencie of Faith.
