The phrase, "I adjure you by the living God," or "I adjure you by God, or whatever.  Mental note: never a good thing.  Unfortunately, the high priest put himself in a small cohort by uttering some derivative of this phrase to the Lord.  Here's some of the other people reportedly "adjured" someone in God's name:

-An Evil Spirit - Mark 5:7

-A Bunch of Mystic Exorcists (The Seven Sons of Sceva)  - Acts 19:13

Not a good club to join.
