15:11, 12 The firstborn son was entitled to two-thirds of his father’s property (Deut. 21:17). Sometimes the father would give the rights to the property (which meant that he could not dispose of it himself, though the son could sell it) and retain the income (if the son sold the property, the buyer could not take possession until the father’s death). But to give the property to one of the sons as in this parable was unusual.
