It will come to be known that the horns of the altar where the horns of the 'unicorn' or 'wild ox' of Ephraim. They were they which symbolized the sacrifical animal the 'bullvine' heffer which is symbolically representing the atonement of the Messiah, the Messiah, and that the Messiah was of the tribe of Ephraim. Thus keeping in mind that it is upon the 'horns of the bullock' that the sins of men are remitted it becomes very significant in may ways respecting the mission and processes of the Lord Jesus Christ and the fulfillment of His Gospel Plan. Consider anew that blessing bestowed upon the head of those of Joseph by Moses in Deuteronomy.

"Let the blessing come upon the head of Joseph, and upon the top of the head of him that was separated from his brethern. His glory is like the firstling of his bullock, and his horns are like the horns of unicorns [wild ox]: with them he shall push the people together to the ends of the earth: and they are the ten thousands of Ephraim and they are the thousands of Mannasseh." ~ Deuteronomy 33:16-17

In applying this concept to the in-gathering and gathering of Israel from the nations of the earth to the end of fulfilling the covenant of Abraham, that through his seed the nations of the earth will be blessed; it seems quite apparent that it is Ephraim assisted by Menasseh, the two blessed sons of Joseph, who are to full fill the covenant of Abraham. That Covenant is the very Covenant of the Fathers which Abraham did seek when he did seek after the blessing of the fathers (Abraham 1:1-4). And it include the blessing in respect to 'the seed', which was that seed of woman that would crush the head of Satan and redeem all of God's children. He is the same as Jesus Christ so fully associated with Ephraim and the seed of Abraham, the promised and blessed seed, even Messiah ben Joseph/Ephraim as well as Messiah ben David—one in the same.

YES the latter-day gathering and filling the earth envisioned by Daniel is universal, unto every nation, kindred, tongue and people who ever have, do, and will live upon the face of the earth under the creation of Jehovah under the direction of his Father Elohim (John 1:1-4 & Eusebius EHC Book I, chapter 2:1-3). And that gathering unto Christ of the blessing of all the nations of the earth according to the covenant blessing of Abraham significantly rests on the back of the symbolic oxen of the tribe of Ephraim as held by the baptismal fonts* of the LDS Temples. And those temples' work for the dead which will continue on through the 1,000 year millennium until all the work has been done for everyone. It is a testament to the universal salvation of Jesus Christ and how it will work in reference to Jesus' teaching that everyone must be born of the water (baptism) and of the spirit, or else they can not enter into the Kingdom of Heaven (John 3:5). These are the 'unicorns' of Ephraim and Jesus Christ, even Messiah ben Ephraim - David - Joseph. Note: The LDS (Mormons) are the only Christians who believe in salvation for the death through baptism for the dead (1 Corinthians 15:29). [Nauvoo Temple Baptism Font - LDS Temple]

And the gathering will be from the (4) four corners of the earth as so represented on the altar of the temple and tabernacle (the portable temple). In both the in-gatherings and the more general gatherings throughout the world to the four corners of the world, by which the stone cut out of the mountain will fill the earth, the horns of the alter are significantly placed at the four corners of the temple alter upon which the blood of the atonement sacrifice is placed upon the four horns (Ex. 29:12, 30:10; Lev. 4:7, 18, 25, 30, 34; Lev. 8:15, 9:9, 16:18; Ezek. 43:20; see blood 'sprinkle/sprinkled as well). In particular this is done on the 'Day of Atonement' and as the 'sin offering' which is the blood of the scarifice, that of Jesus Christ, being symbolically weightedly placed upon the 'horns of the bullock (unicorn, wild ox, red heffer) of Ephraim which rests upon Jesus Christ, even Messiah ben Joseph/Ephraim.

In addition, it will be found signicant that both Joab (1 Kings 2:28-29) and Adonijah (1 Kings 1:49-51) did flee to the temple and grab the horn of the altar, those horns of the Messiah, not only to claim their innocence before God and for a refuge (Exodus 21:12-14; Psalm 18:2 - 2 Samuel 22:2) against death, but further significant in their attempt was that like David and Solomon, both Adonijah and Joab also had a claim unto the descent of Ephraim of through Oben and Jesse of the birthright promised Messiah ben Epharim and not merely that so associated with Judah. So was Joab free from guilt in the slaying of Absalom (murder)? Certainly Absalom was guilty of ursurping to being king and replacing his father David, but David didn't seem to consider it a service as he sorrowed for the death of his son Absalom despite of his rebellion. So David committed Solomon to kill Joab. I suppose it is left to the Lord to sort that out and who is exactly 'responsible' for the killing of who in that matter.
