(1.) A town in the plain of Judah (Joshua 15:35), originally the residence of one of the Canaanitish kings (10:3, 5, 23). It has been identified with the modern Yarmuk, a village about 7 miles north-east of Beit-Jibrin.
(2.) A Levitical city of the tribe of Issachar (Joshua 21:29), supposed by some to be the Ramah of Samuel (1 Samuel 19:22).
Int. Standard Bible Encyclopedia
(1) A city of the Canaanites in the Shephelah (Joshua 15:35) of Judah whose "king," Piram, joined the league of the "five kings" against Joshua (Joshua 10:3-5), was defeated at Gibeon and slain at Makkedah (10:23). One of the 31 "kings" defeated in Joshua' s campaign (Joshua 12:11). In Joshua 15:35 it is mentioned in conjunction with Adullam, Socoh and Azekah, and in Nehemiah 11:29 with Zorah, Zanoah and Adullam. Cheyne (Encyclopedia Biblica) suggests that the "Maroth" of Micah 1:12 may be a copyist's error for Jarmuth. In Eusebius, Onomasticon (OS2 132 31; 266 38) mention is made of a Iermochos, or Jermucha, 10 Roman miles Northeast of Eleutheropolis (Beit Jibrin), The site of this once important place is Khirbet el Yarmuk, a ruin, with many old walls and cisterns, on the top of a hill 1,465 ft. above sealevel. It is nearly 2 miles Northwest of Belt Nattif, from which it is visible, and 8 1/2 miles, as measured on map, N.N.E. of Belt Jibrin. Compare PEF, III, 128, Sh XVIII.
(2) A city of Issachar belonging to the "children of Gershon, of the families of the Levites" (Joshua 21:29); in the duplicate list in 1 Chronicles 6:73 we have Ramoth, while in the Septuagint version of Joshua 21:29 we have, in different VSS, Rhemmath or Iermoth. In Joshua 19:21 "Remeth" occurs (in Hebrew) in the lists of cities of Issachar; in the Septuagint Rhemmas or Rhamath. The name was probably "Remeth" or "Ramoth," but the place has never been identified with any certainty.
