Mbh 13.61.2a

"'Bhishma said, "O son, a Kshatriya is generally employed in deeds of fierceness. In his case, sacrifices and gifts are regarded as cleansing or sanctifying him. They, that are good and righteous, do not accept the gifts of persons of the royal order, who are given to sinful acts. For this reason, the king should perform sacrifices with abundant gifts in the form of Dakshina.[325] If the good and righteous would accept the gifts made unto them, the Kshatriya, O monarch, should incessantly make gifts with devotion and faith unto them. Gifts are productive of great merit, and are highly cleansing. Observant of vows, one should perform sacrifices and gratify with wealth such Brahmanas as are friends of all creatures, possessed of righteousness, conversant with the Vedas, and preeminent for acts, conduct, and penances. If such Brahmanas do not accept thy gifts, no merit becomes thine. Do thou perform sacrifices with copious Dakshina, and make gifts of good and agreeable food unto those that are righteous. By making an act of gift thou shouldst regard thyself as performing a sacrifice. Thou shouldst with gifts adore those Brahmanas who perform sacrifices. By doing this thou will acquire a share in the merits of those sacrifices of theirs. Thou shouldst support such Brahmanas as are possessed of children and as are capable of sending people to Heaven. By conducting thyself in this way thou art sure to get a large progeny--in fact as large a progeny as the Prajapati himself. They that are righteous support and advance the cause of all righteous acts. One should, by giving up one's all, support such men, as also those that do good unto all creatures. Thyself being in the enjoyment of affluence, do thou, O Yudhishthira, make unto Brahmanas gifts of kine and bullocks and food and umbrellas, and robes and sandals or shoes.
