Passage
And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
1 Thessalonians 4:9 But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.
1 Thessalonians 4:10 And indeed ye do it toward all the brethren which are in all Macedonia: but we beseech you, brethren, that ye increase more and more;
1 Thessalonians 4:11 And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
1 Thessalonians 4:12 That ye may walk honestly toward them that are without, and that ye may have lack of nothing.
1 Thessalonians 4:13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
The verse centers on "study", "quiet", "business", "hands", and "commanded". 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 "And indeed ye do it toward all..." into verse 12's "That ye may walk honestly toward them...", 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.
