Genesis 49:8-10
Judah, thou [art he] whom thy brethren shall praise: thy hand [shall be] in the neck of thine enemies; thy father's children shall bow down before thee. ⁹Judah [is] a lion's whelp: from the prey, my son, thou art gone up: he stooped down, he couched as a lion, and as an old lion; who shall rouse him up? ¹⁰The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him [shall] the gathering of the people [be].

Hebrews 7:14
For [it is] evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood. (KJV)

Isaiah 11:1-2
And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots: 2 And the spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the LORD; (KJV)

Revelation 5:8-14
And when he had taken the book, the four beasts and four [and] twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints. ⁹And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation; ¹⁰And hast made us unto our God kings and priests: and we shall reign on the earth. ¹¹And I beheld, and I heard the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands; ¹²Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing. ¹³And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, [be] unto him that sitteth upon the throne, and unto the Lamb for ever and ever. ¹⁴And the four beasts said, Amen. And the four [and] twenty elders fell down and worshipped him that liveth for ever and ever. (KJV)

6. kings = the Greek word for "kingdom." He has made us a kingdom.
      
7. imp. "we shall reign on the earth," is in the Greek, present, not future.
   they reign = basileuousin = present, active, indicative, futuristic use. Jesus is now reigning over His Kingdom!

For he must reign, till he hath put all enemies under his feet. (KJV)

The word, "on," is epi (ep-ee') = a preposition with many variations of meaning, including, "over," "in," "on behalf," etc. Williams translates it as "over." Each child of God, the saved, are now priests in His Kingdom and are reigning in authority with Him.

Luke 10:17-20
And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name. ¹⁸And he said unto them, I beheld Satan as lightning fall from heaven. ¹⁹Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you. ²⁰Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.

Matthew 16:19
And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven. (KJV)

Matthew 28:18-20
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. ¹⁹Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: ²⁰Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, [even] unto the end of the world. Amen. (KJV)

Romans 8:19-21

(KJV)
