Does anyone have a clue what this scripture means?

[UtahDan]

3 Nephi 1:14

14 Behold, I come unto my own, to fulfil all things which I have made known unto the children of men from the foundation of the world, and to do the will, both of the Father and of the Son—of the Father because of me, and of the Son because of my flesh. And behold, the time is at hand, and this night shall the sign be given.

I have thought hard about this and can't come up with anything definitive about what the bold language after the hyphen means. Does anyone know? Thanks in advance.
