Isaiah 30:16-17

ASV(i) 16 but ye said, No, for we will flee upon horses; therefore shall ye flee: and, We will ride upon the swift; therefore shall they that pursue you be swift. 17 One thousand [shall flee] at the threat of one; at the threat of five shall ye flee: till ye be left as a beacon upon the top of a mountain, and as an ensign on a hill.
