Reference: Bethmarcaboth
Fausets
("house of the chariots".) A town of Simeon, in the extreme S. of Judah (Jos 19:5; 1Ch 4:31). Depots or stations of chariots were required in Solomon's reign, when a regular trade in them was carried on with Egypt (1Ki 9:19). As Madmannah appears instead of Bethmarcaboth in the list Jos 15:30-31, possibly Bethmarcaboth was substituted for Madmannah in Jos 19:5, in Solomon's times.
