1 Timothy 6:20-21

To conclude all: O Timothy, keep that which is committed to thy trust The original expression, την παρακαταθηκην φυλαξον, is, literally, guard the deposite; namely, the purity of gospel doctrine, with the dispensation of which thou art intrusted; avoiding profane and vain babblings See 1 Timothy 1:4; 1 Timothy 4:7; and oppositions of science falsely so called Such philosophical disquisitions and debates, as both contradict one another, and were contrary to the truth, though reckoned high points of knowledge. Though it is not certain that the name of Gnostics, or the knowing men, was used in the church so early to denominate a distinct sect, yet it is highly probable that they who opposed the apostle made extraordinary pretences to knowledge, and this text seems sufficient to prove it. Indeed, most of the ancient heretics were great pretenders to knowledge. Which knowledge, some teachers professing to have attained, (1 Timothy 1:6,) have erred concerning the faith Have departed from the true Christian doctrine, some entirely forsaking it, and others corrupting it with gross adulterations. Grace be with thee To guide, in all things, thy judgment and thy conduct. This epistle being chiefly designed for Timothy's own use, no salutations were sent to any of the brethren at Ephesus.
