Nehemiah 4:18 KJV

16And it came to pass from that time forth, that the half of my servants wrought in the work, and the other half of them held both the spears, the shields, and the bows, and the habergeons; and the rulers were behind all the house of Judah.

17They which builded on the wall, and they that bare burdens, with those that laded, every one with one of his hands wrought in the work, and with the other hand held a weapon.

18For the builders, every one had his sword girded by his side, and so builded. And he that sounded the trumpet was by me.

19And I said unto the nobles, and to the rulers, and to the rest of the people, The work is great and large, and we are separated upon the wall, one far from another.

20In what place therefore ye hear the sound of the trumpet, resort ye thither unto us: our God shall fight for us.
