Wherefore Adonizedek king of Jerusalem sent unto Hoham king of Hebron, and unto Piram king of Jarmuth, and unto Japhia king of Lachish, and unto Debir king of Eglon, saying, Hoham king of Hebron - This city was situated in the mountains, southward of Jerusalem, from which it was about thirty miles distant. It fell to the tribe of Judah.
Piram king of Jarmuth - There were two cities of this name; one belonged to the tribe of Issachar, see Joshua 21:29; that mentioned here fell to the tribe of Judah, see Joshua 15:35; it is supposed to have been about eighteen miles distant from Jerusalem.
Japhia king of Lachish - This city is celebrated in Scripture; in that city Amaziah was slain by conspirators, 2 Kings 14:19. It was besieged by Sennacherib, 2 Kings 18:14, 2 Kings 18:17; and without effect by the king of Assyria, as we learn from Isaiah 37:8 : it was also besieged by the army of Nebuchadnezzar, see Jeremiah 34:7; it also fell to the lot of Judah, Joshua 15:39.
Debir king of Eglon - Where this city was situated is very uncertain; but we learn from Joshua 15:39, that it fell to the lot of the tribe of Judah.
