7 [1] But when Sanballat and Tobiah and the Arabs and the Ammonites and the Ashdodites heard that the repairing of the walls of Jerusalem was going forward and that the breaches were beginning to be closed, they were very angry. 8 And they all plotted together to come and fight against Jerusalem and to cause confusion in it. 9 And we prayed to our God and set a guard as a protection against them day and night. 10 In Judah it was said,[2]"The strength of those who bear the burdens is failing. There is too much rubble. By ourselves we will not be able to rebuild the wall." 11 And our enemies said, "They will not know or see till we come among them and kill them and stop the work." 12 At that time the Jews who lived near them came from all directions and said to us ten times, "You must return to us."[3] 13 So in the lowest parts of the space behind the wall, in open places, I stationed the people by their clans, with their swords, their spears, and their bows. 14 And I looked and arose and said to the nobles and to the officials and to the rest of the people, "Do not be afraid of them. Remember the Lord, who is great and awesome, and fight for your brothers, your sons, your daughters, your wives, and your homes." 15 When our enemies heard that it was known to us and that God had frustrated their plan, we all returned to the wall, each to his work.

Commentary on Nehemiah 4:7-15

(Read Nehemiah 4:7-15)

The hindering good work is what bad men aim at, and promise themselves success in; but good work is God's work, and it shall prosper. God has many ways of bringing to light, and so of bringing to nought, the devices and designs of his church's enemies. If our enemies cannot frighten us from duty, or deceive us into sin, they cannot hurt us. Nehemiah put himself and his cause under the Divine protection. It was the way of this good man, and should be our way. All his cares, all his griefs, all his fears, he spread before God. Before he used any means, he made his prayer to God. Having prayed, he set a watch against the enemy. If we think to secure ourselves by prayer, without watchfulness, we are slothful, and tempt God; if by watchfulness, without prayer, we are proud, and slight God: either way, we forfeit his protection. God's care of our safety, should engage and encourage us to go on with vigour in our duty. As soon as a danger is over, let us return to our work, and trust God another time.
