The Ancient of Days will be on the earth:
"Thus saith the LORD, Go and get a potter's earthen bottle, and take of the ancients of the people, and of the ancients of the priests; And go forth unto the valley of the son of Hinnom, which is by the entry of the east gate, and proclaim there the words that I shall tell thee" (Jer.19:1-2).
The following scene is a prophecy concerning the return of the Lord Jesus to the earth to rule in His kingdom:
"I saw in the night-visions, and, behold, there came with the clouds of the sky one like a son of man, and he came even to the ancient of days, and they brought him near before him. There was given him dominion, and glory, and a kingdom, that all the peoples, nations, and languages should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed" (Dan.7:13).
At Matthew 25:31 the Lord Jesus says that when He comes to the earth then He will sit upon His throne. And the following verse shows Him reigning as King in His earthly Kingdom:
"Behold, the days come, saith the LORD, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth" (Jer.23:5).
That verse is describing the same Kingdom spoken of here:
"And the LORD (JWHW) shall be king over all the earth: in that day shall there be one LORD, and his name one" (Zech.14:9).
And the LORD's one name is:
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit" (Mt.28:19).
