1 Timothy 6:20

O Timothy, guard that which is committed unto thee, turning away from the profane babblings and oppositions of the knowledge that is falsely so called; which some professing have erred concerning the faith. Grace be with you.

Guard that ... is one of the needless revisions in the American Standard Version. As Hervey said, "GUARD for KEEP is hardly an improvement. The meaning for keep is to guard, keep watch over and PRESERVE."[27]

Profane babblings ... This does not refer to teaching that was poorly spoken, outright blasphemous or nonsense. No, this is the apostolic evaluation of the most sophisticated heathen teaching of that generation, as indicated by "knowledge that is falsely so called," which balances and explains it. These entire two verses, according to White, may be considered "a summary of the whole epistle."[28] Hardly any passage in the New Testament has any more relevance for our own generation than does this one. This is the time of the utmost arrogance, pride and conceit of haughty boasters who are shouting in deafening tones from every cultural center on earth that they "KNOW." This is the Neo-Gnosticism of the 20th century. What they profess to know is a lie. Man did not evolve from lower life forms. It does not lie within man to direct his steps; and before the phenomenon has disappeared, the proof of the Scriptures will again be profoundly demonstrated.

Have erred concerning the faith ... As Lenski said:

This warning is not directed to Timothy as though he might lose the faith but is a warning that Timothy is to address to the membership of the churches. (This applies also) to other warnings found in this letter.[29]

Grace be with you ... This very brief benediction is quite similar to the one which concludes the book of Hebrews.

You ... here is plural in the Greek, indicating that the meaning of it here is identical with that in Hebrews where it is rendered "you all." As Gould said, "It is evident that he has the entire church at Ephesus in mind when he pens his parting benediction."[30]
