TO'PHEL (lime), a place east of the Arabah. Deut 1:1. It is identical with the Tufileh of Robinson, a large village with about six hundred houses, a little south-east of the Dead Sea. Numerous springs and rivulets and plantations of fruit trees - apples, apricots, figs, pomegranates, and olives - make the place very attractive, and it might naturally be selected as a landmark.
