Nehemiah 4:17-18, 21

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

So we laboured in the work: and half of them held the spears from the rising of the morning till the stars appeared.
