Revelation 17:12-14, 17

“The ten horns you saw are ten kings who have not yet begun to rule, but they will receive power to rule with the beast for one hour. All ten of these kings have the same purpose, and they will give their power and authority to the beast. They will make war against the Lamb, but the Lamb will defeat them, because he is Lord of lords and King of kings. He will defeat them with his called, chosen, and faithful followers.”

God made the ten horns want to carry out his purpose by agreeing to give the beast their power to rule, until what God has said comes about.
