Daniel 2:32

2:32 As for that statue, its head was of fine gold, its chest and arms were of silver, its belly and thighs were of bronze.

Daniel 2:39

2:39 Now after you another kingdom ¹  will arise, one inferior to yours. Then a third kingdom, one of bronze, will rule in all the earth.

[2:39]  ¹ sn The identity of the first kingdom is clearly Babylon. The identification of the following three kingdoms is disputed. The common view is that they represent Media, Persia, and Greece. Most conservative scholars identify them as Media-Persia, Greece, and Rome.
