1. The exterior line, limit or border of a country, as in Scripture. From the river to the uttermost sea shall your coast be. Deuteronomy 11:24. And ships shall come from the coast of Chittim. Numbers 24:24. Hence the word may signify the whole country within certain limits. Exodus 10:4.
2. The edge or margin of the land next to the sea; the sea-shore. This is the more common application of the word; and it seems to be used for sea-coast, the border of the sea. Hence it is never used for the bank of a river.
3. A side; applied to objects indefinitely, by Bacon and Newton. This is a correct use of the word, but now obsolete.
4. The country near the sea-shore; as, populous towns along the coast
The coast is clear, is a proverbial phrase signifying, the danger is over; the enemies have marched off, or left the coast
