The Brāhmaṇa or the mendicant who comes seeking for food, he shall entertain, to the best of his ability, on being permitted by the Brāhmaṇas.—(243)

Medhātithi’s commentary (manubhāṣya):
‘The Brāhmaṇa’—who may arrive as a guest.

‘The mendicant’—the Brāhmaṇa that may come begging for alms.

‘On being permitted by the Brāhmaṇas,’ busy with eating,

‘he shall entertain,’ according to his ability, i.e., he shall honour them by offering food, or by giving alms in the proper manner. [The permission of the invited Brāhmaṇas is essential, because] on that day, the food has been cooked specially for them.—(243)
