John Wesley on Daniel 2:38

Made thee ruler - He hath given thee absolute dominion of all creatures, men and beasts within the bounds of thy vast kingdom. Thou - He was first in order, as the head is before the other parts, and the vision began in him, and descended downwards to the other three monarchies. He was the head of gold, because of the vast riches wherein this monarchy abounded, and because it stood longest, five hundred years, and was fortunate and flourishing to the last.
