Mbh 13.141.12b

Indeed, to eat after the members of one's family including servants and other dependants, is regarded as one of the special duties of the regenerate householder, who should be conversant with the Vedas. The conduct of husband and wife, in the case of householder, should be equal. He should every day make offerings of flowers and other articles unto those deities that preside over domesticity. The householder should take care that his house is every day properly rubbed (with cowdung and water). He should also observe fasts every day. Well-cleaned and well-rubbed, his house should also be every day fumigated with the smoke of clarified butter poured on his sacred fire in honour of the deities and the Pitris. Even these are the duties appertaining to the householder's mode of life as observable by a regenerate person. Those duties really uphold the world. Verily, those duties always and eternally flow from those righteous persons among the Brahmanas that lead a life of domesticity. Do thou listen to me with concentrated attention, O goddess, for I shall now tell thee what the duties are which appertain to the Kshatriya and about which thou hast asked me. From the beginning it has been said that the duty of the Kshatriya is to protect all creatures. The king is the acquirer of a fixed share of the merits earned by his subjects. By that means the king becomes endued with righteousness. That ruler of men who rules and protects his subjects righteously, acquires, by virtue of the protection he offers to others, many regions of felicity in the world to come. The other duties of a person of the kingly order consist of self-restraint and Vedic study, the pouring of libations on the sacred fire, the making of gifts, study, the bearing of the sacred thread, sacrifices, the performance of religious rites, the support of servants and dependants, and perseverance in acts that have been begun. Another duty of his is to award punishments according to the offences committed.
