"a horn," is used in the plural, as the symbol of strength, (a) in the apocalyptic visions; (1) on the head of the Lamb as symbolic of Christ, Revelation 5:6; (2) on the heads of beasts as symbolic of national potentates, Revelation 12:3; 13:1,11; 17:3,7,12,16 (cp. Daniel 7:8; 8:9; Zechariah 1:18 , etc.); (3) at the corners of the golden altar, Revelation 9:13 (cp. Exodus 30:2; the horns were of one piece with the altar, as in the case of the brazen altar, Exodus 27:2 , and were emblematic of the efficacy of the ministry connected with it); (b) metaphorically, in the singular, "a horn of salvation," Luke 1:69 (a frequent metaphor in the OT, e.g., Psalm 18:2; cp. 1 Samuel 2:10; Lamentations 2:3 ).
