Definition: Here's the answer to your question:

1. The phrase "Mark 7:23" is a phrase found within Mark of the Prophets, which refers to the prophet Samuel who was a prominent figure during the time of Jesus. 2. An intriguing and unsettling example sentence using this term could be from an ancient Greek play called "The Tempest." In this play, the character Prospero describes his relationship with Prosperous, his cousin from his past life, as follows: "I have come to thee, my dear friend, I have come to thee to make thee understand what I have seen: you are in a state of madness. You are speaking to me like a madman, and it is so!" This line highlights the intensity and chaos of Prospero's relationship with his cousin, who, according to Prospero, is experiencing an inner turmoil that seems to be spreading outward towards him.
