kon -sēl ´ (παρακαλύπτω , parakalúptō ): Found but once in the New Testament ( Luke 9:45 ). The primary meaning is to cover by hanging something in front of the object hidden. The purpose of the one concealing is made prominent. There is, therefore, a reserve and studied progress in regard to the statement of facts, that is not always a suppression of truth ( Proverbs 12:16 , Proverbs 12:23 ). God withholds more than He reveals ( Proverbs 25:2; compare Psalm 97:2; 1 Timothy 6:16 ).
