I may be entirely off my beam here, but I'm thinking it's equating children with arrows in a quiver. In order not to be embarrassed when your enemies come calling, it's important to have a lot of children to throw at them. Because that's why God gives us children, so we can send them off to kill and get killed. Don't you kill them in the womb. Wait a bit and use 'em as cannon fodder, or summach.

Christ, man, what kind of wedding was this?!
