Nehemiah 4:16-18

16From that day on, half of my men worked on the wall, and the other half were wearing body armor and holding spears, shields, and bows. The leaders stood behind all the Judeans

17who were rebuilding the wall. The workers who were carrying loads did the work with one hand and held their weapons with the other,

18and each builder had his sword fastened to his side. The man who was supposed to sound the trumpet alarm was with me.
