When the Israelites rebuilt the walls of Jerusalem under the watchful eyes of Nehemiah, they held a working tool in one hand and a weapon in the other. 

Not to say that the bible intended this, I doubt it does, but it sure reminded me that that I must be wary as I work. A ready weapon always in hand to check on the state of my heart and mind, ready to put down any corrupting thoughts and doubts. Striking down ill-intentions, bitterness and ungratefulness. Slaying the occasional surge of laziness when the work at hand requires more of me than I expected. 

Combating the complacency as I fold my hands and look at the accomplished work. Vanquishing the self-congratulation that tells me I've done enough, letting only the joy remain. 

Though my hands will be full and the work made harder, I shall keep my hand on the weapon and my eyes wide open.
