Woe unto him that buildeth his house by unrighteousness, and his chambers by wrong; that useth his neighbour's service without wages, and giveth him not for his work; That saith, I will build me a wide house and large chambers, and cutteth him out windows; and it is ceiled with cedar, and painted with VERMILION. ( Jeremiah 22:13-14 )
