Nehemiah 4:15-16

15And it came to pass, when our enemies heard that it was known unto us, and God had brought their counsel to nought, that we returned all of us to the wall, every one unto his work.

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 armour; and the rulers were behind all the house of Judah.
