Dan. 2:40‑43• 40And the fourth kingdom shall be strong as iron: forasmuch as iron breaketh in pieces and subdueth everything, and as iron that breaketh all these, so shall it break in pieces and bruise.
41And whereas thou sawest the feet and toes, part of potter's clay, and part of iron, the kingdom shall be divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay.
42And as the toes of the feet were part of iron and part of clay, the kingdom shall be partly strong and partly fragile.
43And whereas thou sawest the iron mixed with miry clay, they shall mingle themselves with the seed of men; but they shall not cleave one to another, even as iron doth not mingle with clay. (Dan. 2:40‑43)
Dan. 7:7‑8,19‑26• 7After this I saw in the night visions, and behold, a fourth beast, dreadful and terrible, and exceeding strong; and it had great iron teeth: it devoured and broke in pieces, and stamped the rest with its feet; and it was different from all the beasts that were before it; and it had ten horns.
8I considered the horns, and behold, there came up among them another, a little horn, before which three of the first horns were plucked up by the roots; and behold, in this horn were eyes like the eyes of a man, and a mouth speaking great things.
19Then I desired to know the certainty concerning the fourth beast, which was different from them all, exceeding dreadful, whose teeth were of iron, and its nails of brass; which devoured, broke in pieces, and stamped the rest with its feet;
20and concerning the ten horns that were in its head, and the other that came up, and before which three fell: even that horn that had eyes, and a mouth speaking great things, and whose look was more imposing than its fellows.
21I beheld, and that horn made war with the saints, and prevailed over them;
22until the Ancient of days came, and judgment was given to the saints of the most high places; and the appointed time arrived, and the saints possessed the kingdom.
23He said thus: The fourth beast shall be a fourth kingdom upon the earth, which shall be different from all the kingdoms, and shall devour the whole earth, and shall tread it down, and break it in pieces.
24And as to the ten horns, out of this kingdom shall arise ten kings; and another shall arise after them; and he shall be different from the former, and he shall subdue three kings.
25And he shall speak words against the Most High, and shall wear out the saints of the most high places, and think to change seasons and the law; and they shall be given into his hand until a time and times and a half time.
26And the judgment shall sit, and they shall take away his dominion, to consume and to destroy it unto the end. (Dan. 7:7‑8,19‑26)
