It doesn't finish here. I remember well, Ben, that you are the same guy who asked about the merging of the Davidic Messiah and the Ephraimite Messiah in only one figure. Now, the symbol of that merging is just the
cross:
Ezekiel 37:15-20
15 The word of the Lord came again unto me, saying,
16 Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take another stick, and write upon it, For Joseph, the stick of Ephraim and for all the house of Israel his companions:
17 And join them one to another into one stick; and they shall become one in thine hand.
18 And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these?
19 Say unto them, Thus saith the Lord God; Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, even with the stick of Judah, and make them one stick, and they shall be one in mine hand.
20 And the sticks whereon thou writest shall be in thine hand before their eyes.
The cross is so given by the intersection of the two sticks (respectively of Israel and of Judah) to mean the unity of the Jews that will be realized by the Messiah in the last times.
Et voilà, the same image of two different people unified by a cross is shown again in a Christian writing: Ephesians 2:14-16:
14 For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, 15 by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, 16 and in one body to reconcile both of them to God through the cross, by which he put to death their hostility
