"Temptation" : in this verse has the 'specific passive sense of being lured into sin'.
Verse 10
"Love of money" : or "avarice, miserlines" ; as a 'dictum' linked to evil was widely used by ancient philosophers with various expressions ; written as adjective in and.
"Who alone has immortality": The soul of men, the angels and the body of men after resurrection are immortal, but none of these have immortality of themselves, because they have it from God, who alone originally and essentially has it.
"Dwelling in unapproachable light" : in this current mortal and frail state of men, that even the angels cannot bear, but have to cover their faces with their wings, because God is light itself and fountain of lights to all his creatures.
"Whom no man has seen or can see": none but in Christ, at least spiritually, and that but very imperfectly in the current state: frailty, sin and mortality of human nature must be removed away, to inherit the kingdom of God, and enjoy the beatific vision of him, which no man now does, or can see.
"To whom be honor and everlasting power": which may be regarded either as a wish, that such honor, power, and glory might be ascribed to him, or as an assertion that it is given to him, by the angels as well as the saints in heaven and in earth.
Exhortation for the Wealthy (6:17–19)
This part can be seen as an interlude in the exhortation to Timothy or alternatively the previous exhortation can be seen as an 'interruption' in Paul's discourse on wealth, but in either case, the topic of wealth here seems to be a continuation of the theme of 6:3–10. In this short pericope, the 'sound of riches' is repeated four times, could be heard by those listening to the reading of the epistle: plousiois... ploutou... plousiōs... ploutein, which are, respectively, a personal noun, an objective noun, an adverb, and a verb.
Verse 17
"Command" : This is the fifth of the five times in this epistle Paul uses the forms of the verb parangellō for Timothy to "charge, command or instruct" the people, in this verse: to 'those who are rich'.
Epistolary Closing (6:20–21)
Verses 20–21
"Idle babblings": or "empty chatter"
"Grace": as benediction occurs typically in the last words of Pauline epistles, ordinarily with divine source and the intended recipient, but in this verse and the identical, the divine source is omitted, 'but may be assumed from the pattern elsewhere'.
