Daniel 2:32-33

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. 2:33 Its legs were of iron; its feet were partly of iron and partly of clay. ¹ 

[2:33]  ¹ sn Clay refers to baked clay, which – though hard – was also fragile. Cf. the reference in v. 41 to “wet clay.”
