Exodus 29:12, Horns of the altar. The four horns of the altar of sacrifice was the place where the blood of atonement was sprinkled (also Lev 4:4, 17, 18, 25, 30, 34; 8:15; 9:9; 16:18).
But there’s more. Horn is the Hebrew word qeren meaning “horn, hill or ray.” This word is used to describe the rays of light rays emanating from the face of Moses after his encounter with YHVH (Exod 34:29) and the horns of an animal (Ps 69:31). In ancient cultures, the horn was a metaphor for physical strength or spiritual power (Deut 33:17; 2 Sam 22:3; Ps 18:2). Elsewhere, YHVH is referred to as man’s “horn of salvation” meaning he is the strength of our salvation. The Hebrew word for salvation is yesha meaning “deliverance, rescue, safety, welfare, victory, prosperity.” The root of yesha is the verb yasha meaning “to save, to deliver, to give victory.” Not only is YHVH called our “horn of salvation” in the Tanakh, but this designation is applied to Yeshua as well in the Testimony of Yeshua (Luke 1:69). Interestingly, Yeshua is a derivative of the Hebrew name Yehoshua (or Joshua), which also derives from yasha.
It should be evident from this quick study that the horns of the altar are a picture of Yeshua, who is the horn or strength of our salvation and who shed his blood for our sins on the altar of the cross.
This being the case, why then are there four horns on the altar? This is likely symbolic of the four attributes of Yeshua, even as the four colors of cloth used throughout the tabernacle prophetically symbolize the same thing. Crimson speaks to Yeshua’s humanity, purple to his kingship, blue to his divinity, and white to his sinlessness or righteousness.
Additionally, the Jewish sages view the four horns as symbolizing the four corners of the earth, for, in Hebraic thought, the earth is nothing more than a large altar dedicated to Elohim. (See The ArtScroll Tehilim/Psalms commentary on this verse and notes at Ps 118:27.) The horns on the four corners of the altar could also prophetically point to the fact that Yeshua came to save all humans (who would trust in him) from the four corners of the earth.
