Mahavagga, Khandaka 8, Chapter 2

At that time the king of Kāsi^[1] sent to Jīvaka Komārabhacca a woollen garment made half of Benares cloth . . .^[2]. Then Jīvaka Komārabhacca took that woollen garment made half of Benares cloth and went to the place where the Blessed One was; having approached him, and respectfully saluted the Blessed One, he sat down near him. Sitting near him, Jīvaka Komārabhacca said to the Blessed One: 'Lord, this woollen garment made half of Benares cloth. . . .^[3] has been sent to me by the king of Kāsi. May the Blessed One, Lord, accept this woollen garment, which may be to me a long time for a good and a blessing.' The Blessed One accepted that woollen garment.

And the Blessed One taught (&c., as in chap. I, 34, down to:) and went away.

And the Blessed One, after having delivered a religious discourse in consequence of that, thus addressed the Bhikkhus:

'I allow you, O Bhikkhus, to use woollen garments.'

Buddhaghosa: 'This king was Pasenadi's brother, the same father's son.' He appears to have been a sub-king of Pasenadi, for in the Lohicca-sutta it is stated that Pasenadi's rule extended both over Kāsi and Kosala ('Rājā Pasenadi Kosalo Kāsikosalaṃ ajjhāvasati').

Our translation of aḍḍhakāsikaṃ kambalaṃ is merely conjectural. Buddhaghosa has the following note: 'Aḍḍhakāsiyaṃ, here kāsi means one thousand; a thing that is worth one thousand, is called kāsiya. This garment was worth five hundred; therefore it is called aḍḍhakāsiya. And for the same reason it is said, upaḍḍhakāsinaṃ khamamānaṃ.' Perhaps vikāsikaṃ at VI, 15, 5 may have some connection with the word used here.
