Daniel 2:39

And after thee shall arise another kingdom (s) inferior to thee, and another (t) third kingdom of brass, which shall bear rule over all the earth.

(s) Meaning, the Persians who were not inferior in dignity, power, or riches, but were worse with regard to ambition, cruelty, and every type of vice, showing that the world would grow worse and worse, until it was restored by Christ.

(t) That is, those of the Macedonians will be of brass, not alluding to the hardness of it, but to the vileness with regard to silver.
