1.10.3

Ye ca kho te, bho gotama, muṇḍakā samaṇakā ibbhā kaṇhā bandhupādāpaccā, tehipi me saddhiṃ evaṃ kathāsallāpo hoti, yathariva bhotā gotamenā”ti.

But as to these shavelings, fake ascetics, primitives, black spawn from the feet of our kinsman, I converse with them as I do with the worthy Gotama.”
