These are of one mind, and they give their power and authority to the beast.
In the time of the end, amidst much turmoil and political upheaval, such unity of thought and purpose would be unexpected if it were not for their ultimate control by God. For God has put it into their hearts to fulfill His purpose, to be of one mind, and to give their kingdom to the beast, until the words of God are fulfilled (Rev. Rev. 17:17+). They give their power and authority to the beast so that he can become all in all, being the sole focus both in political and religious realms. Because the Beast accepted the offer from Satan which Jesus refused (Luke Luke 4:6), he is given ultimate authority above all else on eartheven claiming to be God (2Th. 2Th. 2:4). For this to occur requires that all other authorities submit to his rule. Although all ten give their power and authority to the beast, for some unspecified reason the Beast eventually destroys three of the ten horns (Dan. Dan. 7:20).
