‘And the kingdom, and the dominion, and the greatness of the kingdoms under the whole heaven will be given to the people (who consist) of the holy ones of the Most High. His kingdom is an everlasting kingdom, and all dominions will serve and obey him.'
Compare Daniel 7:18. After the persecution the blessing. Those who have been trodden down will be lifted up. They will receive the kingdom, and the dominion and the greatness of the kingdoms under the whole heaven, in other words supreme authority over all things. This is indeed God's promise to His people elsewhere (Ephesians 2:6 with Daniel 1:19-21; Revelation 3:21).
‘The people (who consist) of the holy ones of the Most High.' Thus not earthly Israel, but God's true people, His holy ones, whoever they may be.
We note that this almost parallels what is given to the son of man in Daniel 7:14 (He also receives the glory). The son of man (or ‘The Man') there is in contrast with the wild beasts. The wild beasts are both the kings and their kingdoms, one merges into the other. They both behave like wild beasts, but the true people of God behave like true human beings made in the image of God, and through their representative, the true Man, they receive the dominion. Thus the son of man is both the people's representative and the people themselves. But whereas He receives the dominion at His resurrection, they finally receive the dominion at His return in glory.
