He raiseth up the poor out of the dust, and lifteth up the needy from the dunghill. Psalm 113:7
“He [Jesus] is not born in the midst of gold and riches, but in the midst of dung, in a stable where our sins were filthier than the dung. He is born on a dunghill in order to lift up those who come from it: From the dunghill he lifts up the poor.”
