[In] a place in which it is the custom to sell small livestock to idolators, it is permitted to sell [them]; [in] a place in which it is the custom not to sell, it is not permitted to sell. But in every place it is forbidden to sell them large livestock, calves or foals, [whether] whole or maimed. R’ Yehudah permits in the case of a maimed one; and Ben Beseirah permits in the case of a horse.

One may not sell them bears or lions, or anything that has in it [the potential] to cause injury to the public. One may not build with them a basilica, a scaffold, or a stadium, or a platform; but one may build with them bimosyaos and bathhouses. When they reach the vault in which they place an idol, it is forbidden to build.
