Daniel 2:34-35

Thou sawest till a stone was cut out without hands, which smote the image, &c. Here the whole image is represented as destroyed by a great stone falling upon its feet and breaking them to pieces, whereby the whole image was overset and broken. In like manner the kingdom of Christ, a kingdom of God's own erecting, was to break to pieces and destroy the fourth and last empire, in which the remainder of the others was comprehended, and at length to put an end to all earthly rule, authority, and power, 1 Corinthians 15:24. The Jews, as well as Christians, agree that by the stone here is meant the Messiah, or his kingdom, and indeed it is a very apt description of it; for without any visible means, or adequate assistance of human power, it arose, prevailed mightily, and increased to a high degree of strength and greatness, and will still increase, until it become superior to, and swallow up, all the kingdoms of the earth. Then was the iron, the brass, &c., broken to pieces, and became like the chaff, &c. There was no sign or remainder left of their former greatness. The same expression is used by Isaiah 41:15, where see the note. The expressions in both places allude to the thrashing-floors in the eastern countries, which were usually placed on the tops of hills. And the stone that smote the image became a great mountain, &c. This denotes the advancement and increase of Christ's kingdom, that it should from small beginnings proceed to fill the whole earth; as if a stone by degrees should grow to a mountain. Thus Christ is described as going forth conquering and to conquer, Revelation 6:2. Christ, the foundation of the church, is often described as a stone: see Isaiah 28:16; Zechariah 3:9, and the church in its flourishing state is represented as a mountain, Isaiah 2:2; Ezekiel 20:40; Revelation 21:10.
