The rebuilding of the walls by Nehemiah, God's businessman, made possible the revival of the Word under Ezra the priest.
God uses His kingdom business sons and daughters to open up, by practical means, opportunities for sowing His Word in the hearts of
the people.
See the many causes of delight in this gripping scene.
It was the time of the feast of trumpets (Leviticus 23:24 ). How special to begin a new civil year with the blowing of the trumpet
for a time of holy convocation.
How important it is that God's business people begin new rounds of secular work, by marking them as sacred to the Lord, knowing that
all must be done to the glory of God.
What a gathering to warm the heart. "All" the people together, and how appropriate the place, in front of the Water Gate. This was the
place where the written Word of God was given to them as living water.
This could only be a move of God's Spirit. Here was a people lax in keeping God's Word, yearning after its instruction. Building for
God under Nehemiah's zealous leadership, gave the Holy Spirit opportunity to stir desire in the people for better things, like the living
Word.
It was read "from the morning until midday" (Nehemiah 8:3 KJV) by Ezra and his assistants (Nehemiah 8:7 ), and was
accompanied by exposition (Nehemiah 8:7-8 ).
Here are essentials to good teaching:
Standing up indicated special respect for the Word, and readiness to hear and obey it.
They were attentive to the Word for six hours. Both teacher and people were prepared for the Word through worship (Nehemiah
8:6 ).
6. HIS DELIGHT (Nehemiah 8:1 - 10:39)
6.1. IN THE READING OF THE WORD OF THE COVENANT (Nehemiah 8:1-8)
Since the beginning of the book of Nehemiah, we have heard nothing of Ezra. It may be that he had
returned to the king of Persia to make a report of his work. We cannot blame him for not building the walls, since he had not been
authorized to do this, nor did he hold the position of governor. Nehemiah was called of God to rebuild the walls of the city, while Ezra
was the priest whose task was to teach the law. God calls each man to his own work, and equips him for this. J. Stafford Wright.
