Ephratah
fruitful. (1.) The second wife of Caleb, the son of Hezron,
mother of Hur, and grandmother of Caleb, who was one of those
that were sent to spy the land (1 Chr. 2:19, 50).
(2.) The ancient name of Bethlehem in Judah (Gen. 35:16, 19;
48:7). In Ruth 1:2 it is called "Bethlehem-Judah," but the
inhabitants are called "Ephrathites;" in Micah 5:2,
"Bethlehem-Ephratah;" in Matt. 2:6, "Bethlehem in the land of
Judah." In Ps. 132:6 it is mentioned as the place where David
spent his youth, and where he heard much of the ark, although he
never saw it till he found it long afterwards at Kirjath-jearim;
i.e., the "city of the wood," or the "forest-town" (1 Sam. 7:1;
comp. 2 Sam. 6:3, 4).
