In the book of Nehimiah, think I spelled it correctly, men, women and children were building a wall, that's hard labor, not exactly sure if it was around Jerusalem, but it was construction work, they didn't complete it because of violence from the opposing sides, then they went back to working on it, and the Lord instructed, that every man, women, and child, be with a sword at their side, against those who would want to stop them again, not to retreat, but to fight.
