The Greek form of the Hebrew word Jezreel. The "great plain of Esdraelon" is also known in the O.T. as the "valley of Megiddo"; it separates the hills of Samaria from those of Galilee, and is the most fertile part of Palestine. It was crossed by several important highways, and for that reason often provided a battleground (Judg. 4; Judg. 5; Judg. 7; 1 Sam. 31; 2 Chr. 35: 20-27; cf. Rev. 16: 16).
