1) “In order to isolate the Jews from every source of help from the local population, severe penalties have been introduced for extending such help to them. In that part of Yugoslavia designated as Serbia, the military commander issued an order dated December 22, 1941, imposing the death penalty on any person who shelters or hides Jews or accepts any object of value from Jews for safekeeping.”
