17 They all built the wall and those who bore burdens loaded themselves; everyone with one of his hands worked in the work, and with the other held his weapon;
18 and the builders, everyone had his sword girded by his side, and so built. He who sounded the trumpet was by me.
19 I said to the nobles, and to the rulers and to the rest of the people, The work is great and large, and we are separated on the wall, one far from another:
20 in whatever place you hear the sound of the trumpet, resort you there to us; our God will fight for us.
21 So we worked in the work: and half of them held the spears from the rising of the morning until the stars appeared.
