Charles Ellicott 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)

And this I speak for your own profit.—The reference is to the preceding passage, commencing with 1 Corinthians 7:32; and the writer explains that these instructions are given, not to please himself, but for (emphatically) your own advantage; not to entangle you in a noose, and so take away your liberty, but with a view to comeliness (or, honesty,Romans 13:13), and to your waiting upon the Lord without being distracted by earthly things (as, in Luke 10:40, Martha was cumbered).
