A quick search of "tahkemoni my friends face" reveals a couple results to seem to look legit. The book of Tahkemoni is originally Hebrew so translations may differ. As far as I can tell without buying the book and checking, it seems legit.
I searched two differing pdf english translations for different wordings of the quote and couldn't find it. I was kinda hoping someone might be able to cite the specific page as I wanna read the rest of the context if there's any to be found.
