Jamieson, Fausset and Brown on 1 Timothy 4:6

6. If thou put ... in remembrance--rather as Greek, "If thou suggest to (bring under the notice of) the brethren," &c.

these things--namely, the truths stated in 1Ti 4:4, 5, in opposition to the errors foretold, 1Ti 4:1-3.

minister--"servant."

nourished up--The Greek is present, not past: "continually being nourished in" (2Ti 1:5; 3:14, 15).

the words of faith--rather, "the words of the faith" (compare 1Ti 4:12).

good doctrine--"the good teaching." Explanatory of "the faith," in opposition to the "teachings of demons" (English Version, "doctrines of devils," 1Ti 4:1) which Timothy was to counteract. Compare "sound doctrine" (1Ti 1:10; 6:3; Tit 1:9; 2:1).

whereunto thou hast attained--"the course of which thou hast followed"; hast followed along by tracing its course and accompanying it [Alford]. Thou hast begun to follow up [Bengel]. The same Greek occurs, "thou hast fully known" (2Ti 3:10), "having had perfect understanding" (Lu 1:3). It is an undesigned coincidence that the Greek verb is used only by Paul and Paul's companion, Luke.
