What job does Schmuel and Yitzchak have? In the devil's arithmetic

Schmuel was a farmer while Yitzchak was a butcher.

Explanation:

In Jane Yolen's The Devil's Arithmetic, the story revolves around the issue of the Holocaust and the evils done to the Jews. The plot moves from a modern-day American girl's life to the past during the Nazi's persecution of the Jews in Germany.

Schmuel is the uncle of Chaya / Hannah who is to get married to the "jewel Fayge". He works on the fields with his "two fine workhorses, and twenty acres of land", and "smelled of sweat and grass and horses". On the other hand, Yitzchak is the butcher in Chaya's village. He loves Gitl, Chaya's aunt, and Schmuel's sister.
