Where does Buddha mention about Sanatana dharma (Hinduism)?

Hindupedia states, on its page about the [Sanātan Dharma principle](http://hindupedia.com/en/San%C4%81tan_Dharma_principle#Buddhism) , that: > Although Buddha usually spoke of the Sanātan Dharma, he sometimes used other synonymous terms for "Sanātan Dharma," such as "Akaliko Dharma," and "Poranako Dharma." Can I know the all the verse numbers of scriptures, where Buddha mentioned "Sanātan Dharma" "Akaliko Dharma" and "Poranako Dharma." ?
