I did a little research based on your recommendations and I think I understand the origin of the hatred a little better.
Basically it mostly stims from usury.
And the poor Jews got a two fer from it.
The church taught that usury was sinful from the pews, and it’s fairly normal to resent those you owe money too.
Since Jews were the only group basically allow to charge interest they got despised by both groups. Plus killing the person you owe money or driving them out of town, ect has the benefit of wiping out your debt!
It’s no wonder in hindsight why the Jews have been so singled out for hatred as compared to other groups.
Thanks for the information.
I suggest more research. To call one factor, usury, the sole cause of a complex and recurring phenomenon is simplistic and requires one to ignore the numerous instances where the correlation doesn’t work.

Mein Kampf makes no mention of Usury as a cause for Hitler’s development as an anti-Semite. Although it is a recurring theme in Pound’s Cantos, it is more aimed at Britain than the Jews.
