#leviticus 17:3-5 is a prohibition of sacrifice away from the Temple/Tabernacle, not of the slaughter of everyday meat animals. While in the wilderness, all animals had to be slaughtered at the Tabernacle, but once Israel entered the Promised Land, they could resume slaughtering animals for meat wherever they lived. The Wilderness was a training period in which God worked to break the bad habits the people had learned from Mesopotamia and Egypt.
