Nehemiah 4:9-14

Now when our enemies heard that their plan was known to us, and that God had frustrated it, we all returned to the wall, each to his work. From that day on, half of my men were doing the work, while half of them took hold of the spears, shields, bows and breastplates, and the leaders were behind the entire house of Judah. Those building the wall and those bearing heavy burdens kept one hand on the work and the other holding a weapon. So each of the builders had his sword strapped to his side while they were building, and the shofar blower was beside me. Then I said to the nobles, the rulers and the rest of the people, “The work is extensive and spread out, and we are widely separated from one another on the wall. Wherever you hear the sound of the shofar, join us there. Our God will fight for us!”
