Acts 2:37

They were pricked in their heart. — The verb occurs here only in the New Testament, and expresses the sharp, painful emotion which is indicated in “compunction,” a word of kindred meaning. A noun derived from it, or possibly from another root, is used in Romans 11:8 in the sense of “slumber,” apparently as indicating either the unconsciousness that follows upon extreme pain, or simple drowsiness. In “attrition” and “contrition” we have analogous instances of words primarily physical used for spiritual emotions.
