Few prophetic phrases are quoted more often than Jesus’ words in Matthew 24:36: “Now concerning that day and hour no one knows.” Some believers use this verse to discourage any study of Bible prophecy, as though Jesus meant, “Do not ask, do not search, do not discern.” Others move in the opposite direction and claim Jesus was giving a hidden Jewish clue to the Feast of Trumpets, also called Yom Teruah and later associated with Rosh Hashanah.
