Horn:

Trumpets were at first horns perforated at the tip, used for various purposes (Jos 6:4,5).

Flasks or vessels were made of horn (1Sa 16:1,13; 1Ki 1:39).

But the word is used also metaphorically to denote the projecting corners of the altar of burnt offerings (Exd 27:2) and of incense (30:2). The horns of the altar of burnt offerings were to be smeared with the blood of the slain bullock (29:12; Lev 4:7-18). The criminal, when his crime was accidental, found an asylum by laying hold of the horns of the altar (1Ki 1:50; 2:28).

The word also denotes the peak or summit of a hill (Isa 5:1, where the word "hill" is the rendering of the same Hebrew word).

This word is used metaphorically also for strength (Deu 33:17) and honour (Job 16:15; Lam 2:3). Horns are emblems of power, dominion, glory, and fierceness, as they are the chief means of attack and defence with the animals endowed with them (Dan 8:5,9; 1Sa 2:1; 16:1,13; 1Ki 1:39; 22:11; Jos 6:4,5; Psa 75:5,10; 132:17; Luk 1:69, etc.). The expression "horn of salvation," applied to Christ, means a salvation of strength, or a strong Saviour (Luk 1:69). To have the horn "exalted" denotes prosperity and triumph (Psa 89:17,24). To "lift up" the horn is to act proudly (Zec 1:21).

Horns are also the symbol of royal dignity and power (Jer 48:25; Zec 1:18; Dan 8:24).
