-After the first year they stopped bringing the karbon pesach (Passover
sacrifice) until they left the desert.
-In addition there were no personal sacrifices such as shilomim offered
during all these years.
-The reason for this is, G-D's in the mishkan at this point was so immense
more then any other time in history.
-Due to the awesome - fearsome presents of G-D no one could bring himself
to offer a personal, individual sacrifice.
