Midrash su Ezechiele 28:26

Another interpretation: Why was it likened to iron and clay? Just as iron is hard, so is this wicked kingdom hard. And why is it like clay? Because the Holy One is going to break it like clay, as stated (in Is. 30:14): HE SHALL BREAK IT AS A POTTER'S VESSEL IS BROKEN…. Now < Daniel > had seen the Messianic King, as stated (in Dan. 2:34): YOU LOOKED ON UNTIL A STONE WAS CUT OUT WITHOUT THE USE OF HANDS…. Resh Laqish said: This <stone> is the Messianic King. (Ibid., cont.:) THEN IT STRUCK THE STATUE ON ITS FEET, <i.e., struck> all the kingdoms, which were set in the statue. Now by virtue of what is the Messianic King likened to a stone (even)? By virtue of Jacob, < of whom >²⁷“Of whom” is the reading in Tanh., Exod. 7:7. it is stated (in Gen. 49:24): FROM THERE <COMES> THE SHEPHERD, THE ROCK (even) OF ISRAEL²⁸In the biblical context these words would naturally refer to the Holy One, but the midrash understands them as an allusion to Jacob, as does Rashi, ad loc. So also below, 9:12. (Dan. 2:45:) < BECAUSE YOU SAW> THAT A ROCK (even) WAS CUT FROM THE MOUNTAIN, so that it consumes the whole world, as stated (in Is. 11:4): AND HE SHALL SMITE THE EARTH WITH THE ROD OF HIS MOUTH. In that hour Israel shall dwell in tranquillity and security, as stated (in Ezek. 28:26:) AND THEY SHALL DWELL ON IT (their own soil) IN SECURITY.

Another explanation. He is likened to stone because it destroyed a heart of stone, as it is written: And I will remove the stony heart out of their flesh, and will give them a heart of flesh (Ezek. 36:21). Which smote the image (Dan. 2:34) indicates that He will put an end to all the nations, as is said: And he shall smite the land with the rod of His mouth (Isa. 11:4). At that time Israel will dwell in ease and security in the world, as it is stated: And they shall dwell safely therein, and shall build houses, and plant vineyards therein; yea, they shall dwell safely (Ezek. 28:26).
