The Quiverfull movement is an evangelical Christian view that children are blessings from God and people should "be fruitful and multiply" according to the word of the Bible. "Quiverfull" comes from Psalm 127, which reads, "Like arrows in the hands of a warrior are sons born in one's youth. Blessed is the man whose quiver if full of them." People in the Quiverfull movement do not practice birth control and leave it to God to decide how many children they will have.
