"to call upon," has the meaning "appeal" in the Middle Voice, which carries with it the suggestion of a special interest on the part of the doer of an action in that in which he is engaged. Stephen died "calling upon the Lord," Acts 7:59 . In the more strictly legal sense the word is used only of Paul's "appeal" to Caesar, Acts 25:11,12,21,25; 26:32; 28:19 . See CALL (upon), SURNAME. See also eperotema, under ANSWER.
