Albert Barnes Commentary 1 Corinthians 7:35

"And this I say for your own profit; not that I may cast a snare upon you, but for that which is seemly, and that ye may attend upon the Lord without distraction." — 1 Corinthians 7:35 (ASV)

For your own profit. That you may avail yourselves of all your advantages and privileges, and pursue such a course as will tend most to advance your personal piety and salvation.

Not that I may cast a snare upon you. The word rendered snare (brocon) means a cord, a rope, or a bond; and its sense is that Paul would not bind them by any rule which God had not made, nor would he restrain them from what is lawful and what the welfare of society usually requires. Paul means that his object in his advice was their welfare; it was not by any means to bind, fetter, or restrain them from any course that would be for their real happiness, but to promote their real and permanent advantage. The idea presented here by the word snare is usually conveyed by the use of the word yoke (Matthew 11:29; Acts 15:10; Galatians 5:1) and sometimes by the word burden (Matthew 23:4; Acts 15:28).

But for that which is comely. (euschmon) This signifies what is decorous, fit, proper, or noble. It is for what is best suited to your present condition and which, on the whole, will be best and most for your own advantage. There would be a fitness and propriety in your pursuing the course he recommended.

That ye may attend upon the Lord. That is, that you may engage in religious duties and serve God.

Without distraction. That is, without being drawn away (aperispastwv), without care, interruption, and anxiety, so that you may be free to engage with undivided interest in the service of the Lord.
