Nehemiah 4:16-21

16From that day on, half of my men did the work, while the other half were equipped with spears, shields, bows and armor. The officers posted themselves behind all the people of Judah 17who were building the wall. Those who carried materials did their work with one hand and held a weapon in the other, 18and each of the builders wore his sword at his side as he worked. But the man who sounded the trumpet stayed with me. 19Then I said to the nobles, the officials and the rest of the people, “The work is extensive and spread out, and we are widely separated from each other along the wall. 20Wherever you hear the sound of the trumpet, join us there. Our God will fight for us!” 21So we continued the work with half the men holding spears, from the first light of dawn till the stars came out.
