A solemn charge by one in authority to another to speak the truth under the obligation of an oath, as when Ahab adjured Micaiah, 1 Kings 22:16 , and when the high priest adjured our Lord. Matthew 26:63 . Also binding a person under a curse to do or not to do the thing enjoined, as in Joshua 6:26; 1 Samuel 14:24 : cf. also Mark 5:7; Acts 19:13 . Also a 'solemn charge,' as in 1 Thessalonians 5:27 , in the margin.
