'Edge' in the Bible

Bare places by [the] Nile will be dried up, by the edge of [the] Nile and all the sown land of [the] Nile; it will be driven about, and {it will be no more}.

We hear songs from the {edge} of the earth: "Glory to the righteous [one]!" But I say, "Ruin to me! Ruin to me! Woe to me! [The] treacherous ones deal treacherously, and [the] treacherous ones deal treacherously [with] treachery!"
