Jamieson, Fausset and Brown on Deuteronomy 12:22-28

22-28. Even as the roebuck and the hart is eaten, so shalt thou eat them, &c.--Game when procured in the wilderness had not been required to be brought to the door of the tabernacle. The people were now to be as free in the killing of domestic cattle as of wild animals. The permission to hunt and use venison for food was doubtless a great boon to the Israelites, not only in the wilderness, but on their settlement in Canaan, as the mountainous ranges of Lebanon, Carmel, and Gilead, on which deer abounded in vast numbers, would thus furnish them with a plentiful and luxuriant repast.
