Ezekiel 8:7-10

Then he brought me to the door of the Temple courtyard, where I could see a hole in the wall. He said to me, “Now, son of man, dig into the wall.” So I dug into the wall and found a hidden doorway. “Go in,” he said, “and see the wicked and detestable sins they are committing in there!” So I went in and saw the walls covered with engravings of all kinds of crawling animals and detestable creatures. I also saw the various idols worshiped by the people of Israel.
