11 And all this time our enemies were saying, "They won't know what hit them. Before they know it we'll be at their throats, killing them right and left. That will put a stop to the work!" 12 The Jews who were their neighbors kept reporting, "They have us surrounded; they're going to attack!" If we heard it once, we heard it ten times. 13 So I stationed armed guards at the most vulnerable places of the wall and assigned people by families with their swords, lances, and bows. 14 After looking things over I stood up and spoke to the nobles, officials, and everyone else: "Don't be afraid of them. Put your minds on the Master, great and awesome, and then fight for your brothers, your sons, your daughters, your wives, and your homes." 15 Our enemies learned that we knew all about their plan and that God had frustrated it. And we went back to the wall and went to work.

16 From then on half of my young men worked while the other half stood guard with lances, shields, bows, and mail armor. Military officers served as backup for everyone in Judah who was at work rebuilding the wall. 17 The common laborers held a tool in one hand and a spear in the other. 18 Each of the builders had a sword strapped to his side as he worked. I kept the trumpeter at my side to sound the alert.

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.

Commentary on Nehemiah 4:16-23

(Read Nehemiah 4:16-23)

We must watch always against spiritual enemies, and not expect that our warfare will be over till our work is ended. The word of God is the sword of the Spirit, which we ought to have always at hand, and never to have to seek for it, either in our labours, or in our conflicts, as Christians. Every true Christian is both a labourer and a soldier, working with one hand, and fighting with the other. Good work is likely to go on with success, when those who labour in it, make a business of it. And Satan fears to assault the watchful Christian; or, if attacked, the Lord fights for him. Thus must we wait to the close of life, never putting off our armour till our work and warfare are ended; then we shall be welcomed to the rest and joy of our Lord.
