Mbh 13.22.23a

"'Bhishma said, "Those Brahmanas that are freed from wrath, that are devoted to acts of righteousness, that are firm in Truth, and that practise self-restraint are regarded as good. By making gifts unto them one acquires great merit. One wins great merit by making presents unto such Brahmanas as are free from pride, capable of bearing everything, firm in the pursuit of their objects, endued with mastery over their senses, devoted to the good of all creatures, and disposed to be friendly towards all. One earns great merit by making gifts unto such Brahmanas as are free from cupidity, as are pure of heart and conduct, possessed of learning and modesty, truthful in speech and observant of their own duties as laid down in the scriptures. The Rishis have declared that Brahmana to be a deserving object of gifts who studies the four Vedas with all their branches and is devoted to the six well-known duties (laid down in the scriptures). One acquires great merit by making gifts unto Brahmanas possessed of such qualifications. The man who makes gifts unto a deserving Brahmana multiplies his merit a thousand-fold. A single righteous Brahmana possessed of wisdom and Vedic lore, observant of the duties laid down in the scriptures, distinguished by purity of behaviour, is competent to rescue a whole race.[210] One should make gifts of kine and horses and wealth and food and other kinds of articles unto a Brahmana that is possessed of such qualifications. By making such gifts unto such persons one earns great happiness in the next world. As I have already told thee even one such Brahmana is fully competent to rescue the entire race to which the giver belongs. What need I say, therefore, O dear son, of the merit of making gifts unto many Brahmanas of such qualifications? In making gifts, therefore one should always select the object to whom the gifts are to be made.
