A good introduction to the ideological framework of the Quiverfull movement, from an op-ed in Newsweek. I have provided an excerpt and link below.
Often, children of the movement are also called "arrows." Quiverfull takes its name from Psalm 127: "Like arrows in the hands of a warrior are sons born in one's youth. Blessed is the man whose quiver is full of them. They will not be put to shame when they contend with their enemies in the gate." A wealth of military metaphors follows from this namesake, as Pride and her fellow advocates urge women toward militant fecundity in the service of religious rebirth: creating what they bluntly refer to as an army of devout children to wage spiritual battle against God's enemies. As Quiverfull author Rachel Scott writes in her 2004 movement book, "Birthing God's Mighty Warriors,"
"Children are our ammunition in the spiritual realm to whip the enemy! These special arrows were handcrafted by the warrior himself and were carefully fashioned to achieve the purpose of annihilating the enemy."(Emphasis mine)
