Nehemiah’s account of this construction project carries a message for us today (NAB):

10
From that time on, however, only half my able men took a hand in the work, while the other half, armed with spears, bucklers, bows, and breastplates, stood guard behind the whole house of Judah
11
as they rebuilt the wall. The load carriers, too, were armed; each did his work with one hand and held a weapon with the other.
12
Every builder, while he worked, had his sword girt at his side. Also, a trumpeter stood beside me,
13
for I had said to the nobles, the magistrates, and the rest of the people: "Our work is scattered and extensive, and we are widely separated from one another along the wall;
14
wherever you hear the trumpet sound, join us there; our God will fight with us."
15
Thus we went on with the work, half of the men with spears at the ready, from daybreak till the stars came out.
16
At the same time I told the people to spend the nights inside Jerusalem, each man with his own attendant, so that they might serve as a guard by night and a working force by day.
17
Neither I, nor my kinsmen, nor any of my attendants, nor any of the bodyguard that accompanied me took off his clothes; everyone kept his weapon at his right hand.
