Jamieson, Fausset and Brown on 1 Chronicles 4:22-23

22-23. had the dominion in Moab, and Jashubi-lehem--"And these are ancient things" seems a strange rendering of a proper name; and, besides, it conveys a meaning that has no bearing on the record. The following improved translation has been suggested: "Sojourned in Moab, but returned to Beth-lehem and Adaberim-athekim. These and the inhabitants of Netaim and Gedera were potters employed by the king in his own work." Gedera or Gederoth, and Netaim, belonged to the tribe of Judah, and lay on the southeast border of the Philistines' territory (Jos 15:36; 2Ch 28:18).
