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.
BSB
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.
