4 verses in the King James Version. Word study for “himself” →
He that saith he abideth in him ought himself also so to walk, even as he walked.
And every man that hath this hope in him purifieth himself, even as he is pure.
He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
