'Last Days' in the Bible

"it shall come to pass in the last days (saith God) I will pour out of my spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men dream dreams:

God who at sundry times, and in divers manners, spake in time past to the fathers by the prophets, hath in these last days spoken unto us by his SON,

and your gold and silver by rust: that rust shall convict you: that rust shall corrode your flesh like a caustic, which you have treasur'd up against the last days.

for they assur'd you, there would be impostors in the last days, who would follow their own impious passions.
