That reminds me of Nehemiah 4:17. They were doing the work of rebuilding and were constantly on guard against attack. Rather than only fight or only work they did both. They used one had to work and the other to hold a weapon against the enemy. It reminds me of that coexistence of being in battle at the same time as doing God’s work. Also, if I’m understanding correctly, they had a horn that they carried so if they had to fight they could blow the horn and help would come.
Anywho, just something that popped into my head 🙂
