Who are 'these kings' in verse 44?

In verse 44, 'these kings' refers to the ten nations of Western Europe, headed up by the Antichrist. They will run their course of seven years, and in their days the God of heaven will set up a kingdom, which shall never be destroyed.

Les explains that 'these kings' are not a vague group but specifically the ten nations of Western Europe, now headed up by the Antichrist. He connects verse 44 to the prophecy that after these kings have run their seven-year course, the God of heaven will set up a kingdom that shall never be destroyed. Les also notes that Revelation puts a thousand-year time element on that kingdom, which is why it is called the millennium.

When are "the days of these kings" in verse 44 according to Les?

The days of these kings occur when the ten nations of Western Europe, headed up by the Antichrist, have completed their seven-year course. At that point, the God of heaven will set up a kingdom that shall never be destroyed, the same earthly kingdom Scripture has described from the beginning.
