'Horns' in the Bible

Because you push with side and shoulder, and gore with your horns all those that have become weak and sick until you have scattered them away,

The altar hearth shall be four cubits high, and from the altar hearth shall extend upwards four horns [one from each corner, each one cubit high].

And you shall take some of its blood and put it on the four horns [of the altar of burnt offering] and on the four corners of the ledge and on the border all around; thus you shall cleanse it (from sin) and make atonement for it.
