Ephesians 5:28

This verse and the following two verses apply the truth just stated in Ephesians 5:25-27. Since in marriage two people become one flesh (Genesis 2:24), in a figurative sense a man’s wife becomes part of his own body. Consequently the husband should love and treat her as he does his own body (cf. Leviticus 19:18).

"As he does not think about loving himself because it is natural, so also, should the husband’s love of his wife be something that is as natural as loving himself." [Note: Hoehner, Ephesians, p. 765.]
