Genesis 1:28:

And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.

In the beginning two were promised to have dominion over every living thing on earth. Judah and Joseph will fulfill this promise in the end as they will rule and reign in the 1000 year millennium plus the season satan is loosed which will probably be 260 years bringing the total dominion of the two witnesses to 1260 years which will be 1 year for each day they ruled and reigned in the 7 year tribulation as we know the two witnesses have dominion for 1260 days.

Then a new heaven and new earth will be created and the promises and covenants will be fulfilled and Jesus will rule and reign on earth amen!!
