Medhātithi’s commentary (manubhāṣya):
A few unfit persons,—such as the blind, and the rest—have been specifically mentioned in the foregoing verses, describing the evil results of giving food to those unworthy of company; apart from these, there are others, the ‘thief,’ and the rest, mentioned in the several contexts; when these are fed, the following things accrue to the giver: viz., fat, blood, flesh, &c. That is, he becomes born as creatures who feed on these things; i.e., such creatures us insects and such carnivorous animals as vultures, and the like.

“The wise”—those learned in the Veda say this.

The upshot of the whole is as follows:—If one feeds such persons as are unworthy of company, the duty of performing the Śrāddha is not accomplished; and its nonperformance leads inevitably to the sin of disobeying an injunction;—specially, as the injunction of Śrāddha is absolutely obligatory.—(182)
