Nehemiah 4:15-18 New Revised Standard Version (NRSV)
15 When our enemies heard that their plot was known to us, and that God had frustrated it, we all returned to the wall, each to his work. 16 From that day on, half of my servants worked on construction, and half held the spears, shields, bows, and body-armor; and the leaders posted themselves behind the whole house of Judah, 17 who were building the wall. The burden bearers carried their loads in such a way that each labored on the work with one hand and with the other held a weapon. 18 And each of the builders had his sword strapped at his side while he built. The man who sounded the trumpet was beside me.
