'Last Days' in the Bible

God said that 'in the last days [of the Jewish nation?] I will pour out My Holy Spirit upon all people [i.e., both Jews and Gentiles], and your sons and daughters will speak out [in prophecies] and your young men will see [supernatural] visions, and your old men will have [supernatural] dreams.

But you should know this: There will be terrible times in the last days [of the Christian age].

Your gold and silver have tarnished and their tarnish will be a testimony against you [i.e., you have hoarded your wealth instead of using it to benefit others], and they will devour your flesh as fire [i.e., your riches will ultimately consume you]. You have hoarded up your riches in these last days.
