Edge
Edge with reference to the sword, is the rendering ,of פֶּה, peh, mouth (like στόμα, Lu 21:24; Heb 11:34), or fem. פֵּיָה, peyah' (Jg 3:16); also פָּנַים panim', face (Ec 10:10); poet. צוּר, tsur, a rock, hence sharpness (Ps 89:43): elsewhere, in the sense of brink or margin; it corresponds to שָׁפָה saphah', ip; and to קָצָה atsah', קָצֶה , kastek', or קצוֶה kitsveh', extremity (Ex 28:7; Ex 39:4; Ex 13:20; Ex 21:5; Ex 36:12; Nu 33:6,37; Jos 13:27; Ps 39:4). To "set on edge" is an inaccurate rendering (Jer 31:29-30; Eze 18:2) of קָהָה, kahah, to be blunt (as in Ec 10:10). SEE SWORD.
