With Poṭṭhapāda 33.23

33.23

Ayaṃ dukkhanirodhoti kho, poṭṭhapāda, mayā ekaṃsiko dhammo desito paññatto.

‘All those mendicants, Poṭṭhapāda, are blind, and see not. You are the only one, with eyes to see, among them. Some things, Poṭṭhapāda, I have laid down as, certain, other things I have declared uncertain. The latter are those ten questions that you raised, and for the reasons given I hold them matters of uncertainty. The former are the Four Truths I expounded, and for the reasons given I hold them to be matters of certainty.
