7 And it came to pass, when Sanballat, and Tobijah, and the Arabians, and the Ammonites, and the Ashdodites heard that the walls of Jerusalem were being repaired, that the breaches began to be stopped, then they were very wroth, 8 and conspired all of them together to come to fight against Jerusalem, and to hinder it. 9 Then we prayed to our God, and set a watch against them day and night, because of them. 10 And Judah said, The strength of the bearers of burdens faileth, and there is much rubbish; so that we are not able to build at the wall. 11 And our adversaries said, They shall not know, neither see, till we come into the midst of them and kill them, and put an end to the work. 12 And it came to pass that when the Jews that dwelt by them came and told us so ten times, from all the places whence they returned to us, 13 I set in the lower places behind the wall in exposed places, I even set the people, according to their families, with their swords, their spears and their bows. 14 And I looked, and rose up, and said to the nobles, and to the rulers, and to the rest of the people, Be not afraid of them: remember the Lord who is great and terrible, and fight for your brethren, your sons and your daughters, your wives and your houses. 15 And it came to pass that when our enemies heard that it was known to us, and that God had defeated their counsel, we returned all of us to the wall, every one 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.
