Question: where in the bible does it say a man should take care of his wife?
Answer: Bible Gateway 1 Corinthians 7 :: NIV. Now for the matters you wrote about: It is good for a man not to marry. But since there is so much immorality, each man should have his own wife, and each woman her own husband. The husband should fulfill his marital duty to his wife, and likewise the wife to her husband.
