Will animals sold to Gentiles be used to desecrate Jewish law - or will they be used against Jews, either monetarily or through force? The rabbis consider whether or not the animals are healthy, whether or not the animals can bear children, and whether or not the animals are suitable for work.
A new Mishna teaches:
- we are not permitted to sell lions, bears or other animals that might cause damage to the public to Gentiles
- we may not build buildings, scaffolds, courthouses (for judging capital cases), or stadiums (where people are thrown in and gored by bulls)
- we are permitted to build altars and bathhouses with Gentiles as long as they are not directly used for idolatry
- we are not permitted to help build any place where an idol will be placed
