International Standard Bible Encyclopedia [4]
pon´dẽr : Occurs in the King James Version 5 times in the Book of Proverbs and nowhere else in the Old Testament. In each case it means "to consider carefully," "to weigh mentally." In Proverbs 4:26 and Proverbs 5:21 , the Revised Version (British and American) substitutes "make level." In Proverbs 5:6 , it drops out entirely in the Revised Version (British and American). In Proverbs 21:2 and Proverbs 24:12 , "weigh" is substituted for "ponder." The one New Testament passage is Luke 2:19; here the Revised Version (British and American) has "pondering" where the King James Version has "and pondered."
