“The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.”
King James Version (KJV)
7:4 The wife - the husband - Let no one forget this, on pretence of greater purity.
1Co 7:4 The wife hath not power of her own body, etc. Each sex here is put on exactly the same footing. The body of each belongs to the other, and cannot be yielded to other parties. The spirit of the passage not only forbids adultery, but polygamy.
