Psalms 64:6
They search out iniquities; they accomplish a diligent search: both the inward thought of every one of them, and the heart, is deep.
Simple English
They look for wrongdoings very carefully. They do this thoroughly. They examine not only what people think on the inside but also their hearts, which are very deep.
