What is no rest for the wicked?

"No rest for the wicked" is a phrase that originates from the Bible, specifically the Book of Isaiah 48:22 and 57:21, where it is stated, "There is no peace, saith the Lord, unto the wicked." The phrase has since entered common usage in English to suggest that evildoers will face continual toil or punishment, or in a more secular sense, that a person with many responsibilities or troubles cannot afford to rest.

The phrase has been used in various cultural contexts, including literature, music, and film. For example, it's widely known for being the title of Ozzy Osbourne's 1988 album "No Rest for the Wicked," where the theme aligns with Ozzy's heavy metal persona.

Additionally, it has appeared in other music lyrics and is often used colloquially to express the idea of having a relentless schedule or a lack of respite due to various duties or problems.
