“I always avoid prophesying beforehand, because it is a much better policy to prophesy after the event has already taken place.”
Winston Churchill
“Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.”
Bible
“And the elders of the Jews builded, and they prospered through the prophesying of Haggai the prophet and Zechariah the son of Iddo. And they builded, and finished it, according to the commandment of the God of Israel, and according to the commandment of Cyrus, and Darius, and Artaxerxes king of Persia.”
“Then the prophets, Haggai the prophet, and Zechariah the son of Iddo, prophesied unto the Jews that were in Judah and Jerusalem in the name of the God of Israel, even unto them.”
“Then came Jeremiah from Tophet, whither the LORD had sent him to prophesy; and he stood in the court of the LORD's house; and said to all the people, / Thus saith the LORD of hosts, the God of Israel; Behold, I will bring upon this city and upon all her towns all the evil that I have pronounced against it, because they have hardened their necks, that they might not hear my words.”
“For they prophesy falsely unto you in my name: I have not sent them, saith the LORD.”
“And it came to pass, when all that knew him beforetime saw that, behold, he prophesied among the prophets, then the people said one to another, What is this that is come unto the son of Kish? Is Saul also among the prophets? / And one of the same place answered and said, But who is their father? Therefore it became a proverb, Is Saul also among the prophets? / And when he had made an end of prophesying, he came to the high place.”
