from
Easton's 1897 Bible Dictionary
Sea, The
(Heb. yam), signifies (1) "the gathering together of the
waters," the ocean (Gen. 1:10); (2) a river, as the Nile (Isa.
19:5), the Euphrates (Isa. 21:1; Jer. 51:36); (3) the Red Sea
(Ex. 14:16, 27; 15:4, etc.); (4) the Mediterranean (Ex. 23:31;
Num. 34:6, 7; Josh. 15:47; Ps. 80:11, etc.); (5) the "sea of
Galilee," an inland fresh-water lake, and (6) the Dead Sea or
"salt sea" (Gen. 14:3; Num. 34:3, 12, etc.). The word "sea" is
used symbolically in Isa. 60:5, where it probably means the
nations around the Mediterranean. In Dan. 7:3, Rev. 13:1 it may
mean the tumultuous changes among the nations of the earth.
