International Standard Bible Encyclopedia [3]
en - de´vẽr : The sense of this word has suffered weakening since the time of the King James Version. Then it implied utmost exertion and success; now rather forlorn hope and possible failure. Thus the Revised Version (British and American) reads "giving diligence," "give diligence," for the King James Version "endeavoring," "endeavor," in Ephesians 4:3; 2 Peter 1:15 , respectively; but "endeavored" is suffered to remain in 1 Thessalonians 2:17 ( σπουδάζω , spoudázō , "hasten," "exert oneself"). Compare also Acts 16:10 , the King James Version "endeavored," the Revised Version (British and American) "sought" (Greek zētéō , "seek").
