"And when your people say, 'Why has the Lord our God done all these things to us?' you shall say to them, 'As you have forsaken me and served foreign gods in your land, so you shall serve foreigners in a land that is not yours.'" (Jeremiah 5:19)
The belief in prophets is as old as religion itself, and the tradition of prophets is especially prevalent in Judaism and Christianity, with prophets like Isaiah and Jeremiah being among the most famous historical figures in the Bible. God had prophets like Jeremiah perform symbolic acts that foretold future events, particularly hardships that the Israelites suffered at the hands of the Babylonians and Egyptians. The abilities of the prophets to predict future events have become the primary ways in which contemporary society remembers them, which has ensured that the term prophet (which meant "spokesman" in Hebrew) is now part of the lexicon and means something far different from the ancient definitions.
