Nehemiah 4:15-17

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 all the house of Judah, who were building on the wall. Those who carried burdens were laden in such a way that each with one hand labored on the work and with the other held his weapon.
