17 who were building on the wall. Those who carried burdens were loaded in such a way that each labored on the work with one hand and held his weapon with the other. 18 And each of the builders had his sword strapped at his side while he built. The man who sounded the trumpet was beside me.
Matthew Henry's Commentary on Nehemiah 4:17-18
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.
