Passage
and to study to be quiet, and to do your own business, and to work with your own hands, as we did command you,
and to study to be quiet, and to do your own business, and to work with your own hands, as we did command you,
1 Thessalonians 4:9 And concerning the brotherly love, ye have no need of <FI>my<Fi> writing to you, for ye yourselves are God-taught to love one another,
1 Thessalonians 4:10 for ye do it also to all the brethren who <FI>are<Fi> in all Macedonia; and we call upon you, brethren, to abound still more,
1 Thessalonians 4:11 and to study to be quiet, and to do your own business, and to work with your own hands, as we did command you,
1 Thessalonians 4:12 that ye may walk becomingly unto those without, and may have lack of nothing.
1 Thessalonians 4:13 And I do not wish you to be ignorant, brethren, concerning those who have fallen asleep, that ye may not sorrow, as also the rest who have not hope,
The verse centers on "study", "quiet", "business", "hands", and "command". It is saying that the verse draws attention to "study" and "quiet", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "for ye do it also to all..." into verse 12's "that ye may walk becomingly unto those...", so "study" and "quiet" belong inside that flow. In 1 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "study" and "quiet" with trust shaped by these words, not by a vague optimism outside the passage.
