“Those who flee will stand helpless in Heshbon’s shadow, because fire has gone forth from Heshbon and a flame from within Sihon. It devours the foreheads of Moab and the skulls of the sons of tumult.
KJV
They that fled stood under the shadow of Heshbon because of the force: but a fire shall come forth out of Heshbon, and a flame from the midst of Sihon, and shall devour the corner of Moab, and the crown of the head of the tumultuous ones.
ASV
They that fled stand without strength under the shadow of Heshbon; for a fire is gone forth out of Heshbon, and a flame from the midst of Sihon, and hath devoured the corner of Moab, and the crown of the head of the tumultuous ones.
