Beacon

The beacon image appears at the seam where warning meets desolation: a sign raised on a height — a mountain top, a hill, a fortified high place — to be seen from far off. In the prophets it carries both the loneliness of a remnant and the urgency of an alarm.

A Solitary Marker on a Height

Isaiah's warning to Judah ends with a picture of the people whittled down until only a token is left, conspicuous because so much has fallen away: "A thousand together [will flee] at the threat of one; at the threat of five you⁺ will flee: until you⁺ are left as a beacon on the top of a mountain, and as an ensign on a hill" (Isa 30:17). The beacon and the ensign stand for what is left when the army has dissolved — a single visible marker on the skyline.

A Warning Raised at the Approach of Disaster

Jeremiah's call to flee from Jerusalem pairs the trumpet at Tekoa with a signal raised on Beth-haccherem: "Flee for safety, you⁺ sons of Benjamin, out of the midst of Jerusalem, and blow the trumpet in Tekoa, and raise up a signal on Beth-haccherem; for evil looks forth from the north, and a great destruction" (Jer 6:1). The signal on the high place works in tandem with the trumpet — sound and sight together — to broadcast the approach of the northern invader.
