11 Meanwhile, our enemies were saying, "Before they know what's happening, we will swoop down on them and kill them and end their work." 12 The Jews who lived near the enemy came and told us again and again, "They will come from all directions and attack us!" 13 So I placed armed guards behind the lowest parts of the wall in the exposed areas. I stationed the people to stand guard by families, armed with swords, spears, and bows. 14 Then as I looked over the situation, I called together the nobles and the rest of the people and said to them, "Don't be afraid of the enemy! Remember the Lord, who is great and glorious, and fight for your brothers, your sons, your daughters, your wives, and your homes!" 15 When our enemies heard that we knew of their plans and that God had frustrated them, we all returned to our work on the wall.

16 But from then on, only half my men worked while the other half stood guard with spears, shields, bows, and coats of mail. The leaders stationed themselves behind the people of Judah 17 who were building the wall. The laborers carried on their work with one hand supporting their load and one hand holding a weapon. 18 All the builders had a sword belted to their side. The trumpeter stayed with me to sound the alarm.

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.
