A horn is a sign of power (Deut. 33: 17)—literally of an ox (Num. 23: 22) or metaphorically of a people (1 Kgs. 22: 11). In Dan. 7: 8 the horns refer metaphorically to kings. So the ‘horn of salvation’ (Ps. 18: 2) indicates the saving power of the king. The four horns on the corners of altars (Exod. 27: 2) afforded sanctuary to a fugitive who clung to them. The horn of salvation in Luke 1: 69 (NRSV marg., AV) denotes royal saving power, now belonging to the Messiah.
