Who knows infinity?
?אין סוף - מי יודע
Breishit 41:49 says that when Yosef gathered grain to prepare for the upcoming famine in Egypt, he gathered so much that he stopped counting because there was no number.
It seems that Yosef was attempting to count to infinity but couldn't get there so he stopped somewhere just before it.
Other than Yosef's attempt, please cite other interesting Jewish facts about infinity that you can think of.
