'Sea side' in the Bible

On that day Jesus went out of the house and was seated by the seaside.

And he went out again by the seaside; and all the people came to him, and he gave them teaching.

And again he was teaching by the seaside. And a very great number of people had come to him, so that he got into a boat on the sea and took his seat; and all the people were on the land by the seaside.

So that from one man, who was near to death, came children in number as the stars in heaven, or as the sand by the seaside, which may not be numbered.
