Uttermost
uter-most: A pleonastic compound of a comparative (utter; compare outer) and a superlative (most), in the King James Version used interchangeably with the ordinary superlative forms utmost (compare Mat 12:42; Luk 11:31) and outmost (compare Exo 26:4, Exo 26:10). The Revised Version (British and American) adds still another form, outermost, in 2Ki 7:5, 2Ki 7:8 (the King James Version uttermost). the Revised Version (British and American) has made a few changes to secure a more accurate translation (Jer 9:26; Joe 2:20, etc.) or to give uniformity (Exo 26:4; Mat 5:26; Mat 12:42, etc.), but for the most part has left the King James Version undisturbed.

Uttermost
the neuter of the adjective panteles, “complete, perfect,” used with eis to (“unto the”), is translated “to the uttermost” in Heb 7:25, where the meaning may be “finally;” in Luk 13:11 (negatively), “in no wise.”
“an end,” is rendered “the uttermost” in 1Th 2:16, said of Divine wrath upon the Jews, referring to the prophecy of Duet. 28:15-68; the nation as such, will yet, however, be delivered (Rom 11:26; cp. Jer 30:4-11). The full phrase is eis telos, “to the uttermost,” which is probably the meaning in Joh 13:1, “to the end.”
