But the one who looks intently into the perfect law of freedom, and continues to do so—not being a forgetful hearer, but an effective doer—he will be blessed in what he does.
KJV
But whoso looketh into the perfect law of liberty, and continueth [therein], he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
ASV
But he that looketh into the perfect law, the law of liberty, and so continueth, being not a hearer that forgetteth but a doer that worketh, this man shall be blessed in his doing.
