Uttermost
[ 1,,G3838, panteles ]the neuter of the adjective panteles, complete, perfect," used with eis to ("unto the"), is translated "to the uttermost" in Hebrews 7:25, where the meaning may be "finally;" in Luke 13:11 (negatively), "in no wise."
[ 2,,G5056, telos ]
"an end," is rendered "the uttermost" in 1 Thessalonians 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 (Romans 11:26; cp. Jeremiah 30:4-Jeremiah 30:11). The full phrase is eis telos, "to the uttermost," which is probably the meaning in John 13:1, "to the end."
