Int. Standard Bible Encyclopedia ENDEAVOR en-de'-ver: 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 (spoudazo, "hasten," "exert oneself"). Compare also Acts 16:10, the King James Version "endeavored," the Revised Version (British and American) "sought" (Greek zeteo, "seek").
