'Flame' in the Bible

Strengthen yourselves, sons of Benjamin, From the midst of Jerusalem, And in Tekoa blow ye a trumpet, And over Beth-Haccerem lift ye up a flame, For evil hath been seen from the north, And great destruction.

In the shadow of Heshbon stood powerless have fugitives, For fire hath gone forth from Heshbon, And a flame from within Sihon, And it consumeth the corner of Moab, And the crown of the sons of Shaon.
