Nehemiah 9 - Matthew Henry's Concise Commentary on the Bible

A solemn fast.

The word will direct and quicken prayer, for by it the Spirit helps our infirmities in prayer. The careful study of God's word will more and more discover to us our own sinfulness, and the plenteousness of his salvation; thus it calls us to mourn for sin, and to rejoice in him. Every discovery of the truth of God, should render us more unwearied in attendance on his sacred word, and on his worship. (Ne 9:4-38)
