11 And those who were against us said, Without their knowledge and without their seeing us, we will come among them and put them to death, causing the work to come to a stop. 12 And it came about that when the Jews who were living near them came, they said to us ten times, From all directions they are coming against us. 13 So in the lowest part of the space at the back of the walls, in the open places, I put the people by families, with their swords, their spears, and their bows. 14 And after looking, I got up and said to the great ones and to the chiefs and to the rest of the people, Have no fear of them: keep in mind the Lord who is great and greatly to be feared, and take up arms for your brothers, your sons, and your daughters, your wives and your houses. 15 And when it came to the ears of those who were against us, that we had knowledge of their designs and that God had made their purpose come to nothing, we all went back to the wall, everyone to his work

16 And from that time, half of my servants were doing their part of the work, and half kept the spears and body-covers and the bows and the metal war-dresses; and the chiefs were at the back of the men of Judah. 17 Those who were building the wall and those who were moving material did their part, everyone working with one hand, with his spear in the other; 18 Every builder was working with his sword at his side. And by my side was a man for sounding the horn.

Matthew Henry's Commentary on Nehemiah 4:11-18

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.
