"The borders of the seashore"

1. Alma 22: 27
     27 And it came to pass that the king sent a proclamation throughout all the land, amongst all his people who were in all his land, who were in all the regions round about, which was bordering even to the sea, on the east and on the west, and which was divided from the land of Zarahemla by a narrow strip of wilderness, which ran from the sea east even to the sea west, and round about on the borders of the seashore, and the borders of the wilderness which was on the north by the land of Zarahemla, through the borders of Manti, by the head of the river Sidon, running from the east towards the west—and thus were the Lamanites and the Nephites divided.
2. Alma 50: 15
     15 And they also began in that same year to build many cities on the north, one in a particular manner which they called Lehi, which was in the north by the borders of the seashore.
