Many wonderful idioms gave us the Bible - the most printed book so far. Probably everyone knows the expression "no stone unturned". Consider its meaning, origin and examples.
Origin and Meaning
If the reader wants to see the phrase in the original source, then he should look into the Gospel of Matthew. Don't think that we don't know the exact location of the expression. The phrase "leave no stone unturned" is "at": the Gospel of Matthew, chapter 24, verse 2.
The meaning of it is to destroy to the ground. But it is often used in the meaning of "to smash to the ground." In general - destroy, leave nothing. Even if you don't know history, you can guess. For example, often when buildings are destroyed, the foundation remains of them. And the expression, in turn, suggests that there will not even be building materials. Not leaving a stone unturned means destroying everything to a state of dust.
Use
The expression is not ashamed to be used in public: in speeches, comments, in ordinary conversation between people. Hisespecially loved by sports journalists for the accuracy of the wording. Moreover, various competitions are conducive to biting metaphors. For example, like this: "Inter" defeated "Milan" in the derby; "black-blue" did not leave a stone unturned from the protection of neighbors.
Therefore, even a person who has never opened the Bible, restoring the meaning from the context, can easily answer the question about the meaning of the expression. Of course, you also need to be interested in sports. But now the state program is such that only those who do not turn on the TV are not fond of sports. The rest are more or less up to date.
A separate story is the ideology of "he althy lifestyle", or he althy lifestyle for short. You can treat her as you like, but one thing is indisputable - going to the gym is better than drinking vodka. In other words, we are confident that a he althy lifestyle, using phraseology, will not leave a stone unturned from the bad habits of the nation. True, the main thing is that this whole thing should not be imposed, otherwise there will be no sense. But do not talk about sad things.
