What did the priest in Aushwitz tell Vladek that enabled him to keep going?

I have my book right here, where was this roughly?

Around page 30 or so? Maybe...

Hey there, the priest looks at Vladek's tattoo and tells him that the numbers are auspicious (good luck). He says that they point to Vladek living past the war.

Thank you for all your help! You're a life saver!!

No problems!
