Yiddish proverb translate?

Can someone please tell me the original Yiddish for this proverb?
“If God wants people to suffer he sends them too much understanding.”

No idea, but it sounds like a paraphrase of Ecclesiastes 1:18:

Good question. The internet is full of claims that this is a Yiddish proverb AND it’s full of lists of Yiddish proverbs in the original Yiddish, but this particular one is nowhere to be found in Yiddish. Makes you wonder if it really is a Yiddish proverb.

Anyway, based on my (very limited) knowledge of Yiddish and some googling I’d say it should go something like this:

Az Got menshn krenken volt shikt Er tsu fil fershtain

I hope this at least helps your quest somewhat
