But the poor man had nothing, save one little ewe lamb, which he had bought and nourished up: and it grew up together with him, and with his children; it did eat of his own meat, and drank of his own cup, and lay in his bosom, and was unto him as a daughter. And lay in his bosom - This can only mean that this lamb was what we call a pet or favourite in the family, else the circumstance would be very unnatural, and most likely would have prevented David from making the application which he did, as otherwise it would have appeared absurd. It is the only part of this parable which is at variance with nature and fact.
