John Gill Bible Commentary

The hills melted like wax at the presence of the Lord,.... Kimchi interprets the "hills" of the kings of the wicked; and it was verified in Herod and his nobles, and the citizens of Jerusalem, who, when they heard of the coming of the Messiah, of the birth of the King of the Jews, were exceedingly moved and troubled; their hearts melted like wax within them, Mat 2:1, so when he appeared, in the power of his Gospel, in the Gentile world, and went forth in the ministration of it, conquering, and to conquer, all fled before him; every mountain and island were moved out of their places; and the kings of the earth, and great men, ran to the rocks to hide them from his face, which they could not bear, Rev 6:14, and the like events, and more terrible, will they be, when he comes to destroy antichrist, and especially to judge the world, Rev 16:19. at the presence of the Lord of the whole earth; as Christ is; he is Lord of all, the Prince of the kings of the earth, Act 10:36, Rev 1:5, and as he will show himself to be at the great day; and that is the reason why the proud and lofty, comparable to hills and mountains, shall melt at his presence.
