Adam Clarke on 1 Corinthians 7:34

There is a difference also between a wife and a virgin - That is: There is this difference between a married and an unmarried woman. The unmarried careth (only) for the things of the Lord, having no domestic duties to perform. That she may be holy - separated to Divine employments, both in body and spirit. Whereas she that is married careth (also) for the things of the world, how she may please her husband, having many domestic duties to fulfill, her husband being obliged to leave to her the care of the family, and all other domestic concerns.

On this verse there is a profusion of various readings in MSS., versions, and fathers, for which I must refer to Griesbach, as it would be impossible to introduce them here so as to make them look like sense.
