Nehemiah 4:15-18

When our enemies heard that it was known to us and that God had frustrated their plan, we all returned to the wall, each to his work. From that day on, half of my servants worked on construction, and half held the spears, shields, bows, and coats of mail. And the leaders stood behind the whole house of Judah, who were building on the wall. Those who carried burdens were loaded in such a way that each labored on the work with one hand and held his weapon with the other. And each of the builders had his sword strapped at his side while he built. The man who sounded the trumpet was beside me.
