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. With one of his hands wrought in the work, and with the other hand held a weapon - That is, he had his arms at hand, and was as fully prepared to fight as to work. So Ovid, Epist. xi., Canace Macario, ver. 1: -
Si qua tamen caecis errabunt scripta lituris,
Oblitus a dominae caede libellus erit:
Dextra tenet calamum; strictum tenet altera ferrum:
Et jacet in gremio charta soluta meo.
If streaming blood my fatal letter stain,
Imagine, ere you read, the writer slain.
One hand the sword, and one the pen employs,
And in my lap the ready paper lies.
Dryden.
By this mode of speech Canace does not intimate to her brother Macarius, that she actually held the sword in one hand while she held the pen in the other, but that she had it ready to slay herself as soon as she had written the epistle.
