Hem in

2. Alma 22: 33
     33 And it came to pass that the Nephites had inhabited the land Bountiful, even from the east unto the west sea, and thus the Nephites in their wisdom, with their guards and their armies, had hemmed in the Lamanites on the south, that thereby they should have no more possession on the north, that they might not overrun the land northward.
3. 3 Ne. 4: 16
     16 And in the *twenty and first year they did not come up to battle, but they came up on all sides to lay siege round about the people of Nephi; for they did suppose that if they should cut off the people of Nephi from their lands, and should hem them in on every side, and if they should cut them off from all their outward privileges, that they could cause them to yield themselves up according to their wishes.
