7 But it happened that when Sanballat, Tobiah, the Arabians, the Ammonites, and the Ashdodites heard that the repairing of the walls of Jerusalem went forward, and that the breaches began to be stopped, then they were very angry; 8 and they conspired all of them together to come and fight against Jerusalem, and to cause confusion therein. 9 But we made our prayer to our God, and set a watch against them day and night, because of them. 10 Judah said, The strength of the bearers of burdens is decayed, and there is much rubbish; so that we are not able to build the wall. 11 Our adversaries said, They shall not know, neither see, until we come into the midst of them, and kill them, and cause the work to cease. 12 It happened that when the Jews who lived by them came, they said to us ten times from all places, You must return to us. 13 Therefore set I in the lowest parts of the space behind the wall, in the open places, I set there the people after their families with their swords, their spears, and their bows. 14 I looked, and rose up, and said to the nobles, and to the rulers, and to the rest of the people, Don’t be afraid of them: remember the Lord, who is great and awesome, and fight for your brothers, your sons, and your daughters, your wives, and your houses. 15 It happened, when our enemies heard that it was known to us, and God had brought their counsel to nothing, that we returned all of us to the wall, everyone 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.
