I am pretty sure that this is a biblical reference of some sort that spawned both the card and the song...
They all are in fact a reference to the text in the Book of Isaiah and the Book of Micah. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore. — Isaiah 2:4 & Micah 4:3 Prophesies of a future Messianic Age where there will be peace amongst all humankind.

Description
We have a sizeable army, but I'm afraid the coming showdown with the Neferset hordes will demand that all able-bodied tol'vir of Ramkahen and Orsis join in the fight. I want you to be at the forefront of our recruiting efforts. Go across the river, to the Akhenet Fields, and recruit the laborers that work there.

Item facts are the current retail client’s (ItemSparse); the specialisations for a pick-one item are the ones the Blizzard quest API lists; faction and currency text is the client’s own. Lowest listed price = the US commodity auction house now.
