Bhishma said A cow should never be given to one who is not pious in conduct, or one that is sinful, or one that is covetous, or one who is a liar, or one who does not make offerings to the departed manes and celestials.
भीष्म उवाच असवृत्ताय पापाय लुब्धायानृतवादिने। हव्यकव्यव्यपेताय न देया गौः कथंचन॥
