(Heb. Beyth Pellet, בֵּית פֶּלֶט , House Of Escape, but found only "in pause," Beyth Pallet, בֵּית פּ לֶט [or בֵּיתאּ ]; Sept. Βηθφέλεθ and Βηθφαλάτ or Βαιθφαλάθ ), one of the towns in the extreme south of Judah (i.e. assigned to Simeon), named between Heshmon and Hazar-shual ( Joshua 15:27), and inhabited after the captivity ( Nehemiah 11:26, where it is Anglicized "Beth-phelet"). It corresponds possibly to the "considerable ruin" on Tell El-Kuseifeh (Robinson's Researches, 2, 620), a short distance N.E. of Moladah (Van de Velde, Map ) .

Lieut. Conder suggests (Quarterly Statement of the "Pal. Explor. Fund," January, 1875, p. 26) that from position it might very well correspond to el-Hora (drawing of water), a place remarkable for its number of cisterns and reservoirs, the buildings being of flint throughout.
