Various Bible Commentaries on Women
Being Called the Weaker Vessel (1 Peter 3:7)

“as unto the weaker vessel” Weaker than the husbands, and that both in body and mind, as women usually are. In Scripture any instrument is called a vessel, and the wife is here called so, as being not only an ornament, but a help to the husband and family, Ge 2:18. This he adds as a reason why the husband should give honour to the wife, viz. her being the weaker vessel; weak vessels must be gently handled; the infirmities of children bespeak their pardon when they offend; and those members of the body which we think less honourable, on them we bestow more abundant honour, 1Co 12:23. It is a part of that prudence according to which men should dwell with their wives, to have the more regard to them because of their infirmities, (in bearing with them and hiding them), lest they should be discouraged, if they find their weakness makes them contemptible.

“Here “the weaker”; being so for the most part, both as to strength of body, and endowments of mind; and therefore to be used gently and tenderly, and not be treated with neglect and contempt, or with inhumanity and severity; but as, in every state and condition, the strong are to bear the infirmities of the weak; so a man should bear with, and accommodate himself to the infirmities of his wife, and hide them as much as he can, and not expose them, nor despise her on account of them.”

— Comment on 1 Peter 3:7, from Exposition of the Bible by John Gill (1697-1771)

“It is usual in Scripture to compare man in general unto a vessel: see 1 Samuel 21:5; 1 Thessalonians 4:4; 2 Corinthians 4:7. Hence the woman is called the weaker vessel, because generally she is weaker, both in the faculties of her soul, and the constitution of her body. And in that she is called the weaker vessel, thereby is implied the reason wherefore husbands must so carry themselves…Weaker vessels, as those of glass and earth, we use carefully and tenderly: and so husbands should carry themselves toward their wives.”

This work was also popularly known as the Westminster Annotations, as over half of the commentators were Westminster divines.
