Albert Barnes Commentary 1 Corinthians 7:4

"The wife hath not power over her own body, but the husband: and likewise also the husband hath not power over his own body, but the wife." — 1 Corinthians 7:4 (ASV)

The wife hath not power, etc. By the marriage covenant that power, in this respect, is transferred to the husband.

And likewise also the husband. The equal rights of husband and wife, in the Scriptures, are everywhere maintained. They are to regard themselves as united in the most intimate union, and in the most tender ties.
