Leviticus 6:3

Lost. We acquire no title to the thing by finding it. The Roman law, as well as divines, condemn those who appropriate the thing found to their own use, as guilty of theft, whether they knew to whom it belonged or not; and Plato greatly commends the law of Solon, "Take not what thou didst not put down," a rule which the Dyrbeans and the people of Biblos rigorously observed. We may, however, take up what is lost, (Calmet) and endeavour to find the owner, who must indemnify us for our trouble; and, if we never find him, we are directed to give the price to the poor, for the owner's welfare.
