15 Our enemies found out that we knew about their plot against us, but God kept them from doing what they had planned. So we went back to work on the wall.
16 From then on, I let half of the young men work while the other half stood guard. They wore armor and had spears and shields, as well as bows and arrows. The leaders helped the workers
17 who were rebuilding the wall. Everyone who hauled building materials kept one hand free to carry a weapon.
18 Even the workers who were rebuilding the wall strapped on a sword. The worker who was to blow the signal trumpet stayed with me.
19 I told the people and their officials and leaders, “Our work is so spread out, that we are a long way from one another.
20 If you hear the sound of the trumpet, come quickly and gather around me. Our God will help us fight.”
21 Every day from dawn to dark, half of the workers rebuilt the walls, while the rest stood guard with their spears.
