"Toil and trouble" is a phrase from William Shakespeare's play "Macbeth" that refers to hard work and difficulty. It is often used to describe a situation filled with challenges or obstacles.
It means that trouble is coming. They sing this in Harry Potter #3
MacBeth
The line "Double, double, toil and trouble" was first said by the character of the Second Witch in William Shakespeare's play "Macbeth."
This statement suggests that both trouble and grievous toil can arise from opposite ends of the spectrum: idleness and needless ease on one hand, and excessive work and toil on the other. It implies that a lack of purposeful activity and productivity can lead to problems, just as pushing oneself too hard without necessity can result in suffering. Essentially, balance and moderation in one's approach to work and leisure are key to avoiding unnecessary difficulties.
