The Code of Hammurabi
English, translated by C. H. W. Johns — Johns, The Oldest Code of Laws in the World, Edinburgh, 1903
If a man, in addition to the children which he has possessed, has taken a wife, for his young son has not taken a wife, after the father has gone to his fate, when the brothers divide, from the goods of the father's house to their young brother who has not taken a wife, beside his share, they shall assign him money as a dowry and shall cause him to take a wife.
