Medhātithi’s commentary (manubhāṣya):
Prajāpati, having approached, said to the gods —‘Do not in this way, make the unequal eaual’—i.e., do not establish any such improper equalisation.

Then the gods asked—‘Who there is, then, the superior between the two persons?’

Then Prajāpati answered—‘The food that belongs to the liberal-minded usurer, who is endowed with faith, is purified by faith, while the other food, that belongs to the Vedic scholar, is censured, condemned, by his act (faithlessness).’

This dialogue between Prajāpati and the gods is purely imaginary; all that is meant is that ‘one shall not eat food offered by a person, who, though otherwise qualified, is devoid of faith, while that belonging to the Śūdra shall be eaten, if it is offered with due respect.’—(225)
