This can be verified in Jerimiah 7:21, as well as by
noting that G - d reduced access to sacrifices all through the entire Tanach; originally each man was a priest in his own home, offering sacrifices whenever and
wherever (Cain, Abel, Abraham), but at Mt. Sinai it was reduced to a single place (the tabernacle / temple) and to assigned priests; this was fine for 40 years of wandering, but as soon as they entered «the promised land», the tabernacle traveled with the army, and those
left behind as settlers in the new land had no more access to it.
