Horn: Trumpets were at first horns perforated at the tip, used for various purposes (Joshua 6:4,5) Flasks or vessels were made of horn (1 Samuel 16:1,13; 1 Kings 1:39) But the word is used also metaphorically to denote the projecting corners of the altar of burnt offerings (Exodus 27:2) and of incense (Exodus 30:2) The horns of the altar of burnt offerings were to be smeared with the blood of the slain bullock (Exodus 29:12; Leviticus 4:7-18) The criminal, when his crime was accidental, found an asylum by laying hold of the horns of the altar (1 Kings 1:50) (1 Kings 2:28) The word also denotes the peak or summit of a hill (Isaiah 5:1) where the word "hill" is the rendering of the same Hebrew word. This word is used metaphorically also for strength (Deuteronomy 33:17) and honour (Job 16:15; Lamentations 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 (Daniel 8:5,9; 1 Samuel 2:1; 16:1,13) (1 Kings 1:39; 22:11) (Joshua 6:4,5; Psalms 75:5,10; 132:17; Luke 1:69) etc. The expression "horn of salvation," applied to Christ, means a salvation of strength, or a strong Saviour (Luke 1:69) To have the horn "exalted" denotes prosperity and triumph (Psalms 89:17,24) To "lift up" the horn is to act proudly (Zechariah 1:21) Horns are also the symbol of royal dignity and power (Jeremiah 48:25; Zechariah 1:18; Daniel 8:24)
