'Themselves' in the Bible

Therefore, do not forget that formerly you were Gentiles as to your bodily condition. You were called the Uncircumcision by those who style themselves the Circumcised--their circumcision being one which the knife has effected.

Such men being past feeling have abandoned themselves to impurity, greedily indulging in every kind of profligacy.

So too married men ought to love their wives as much as they love themselves. He who loves his wife loves himself.
