Proverbs 2:15

Whose ways are crooked, and they froward in their paths:

Whose ways are crooked,.... Which swerve from and are not agreeably to the rule of the divine word, either the law of God or the Gospel of Christ; sin is an aberration, a straying from the rule of God's word, a transgression of his law; and a walk in it is unbecoming the Gospel of Christ; it has many serpentine windings and turnings in it; full of distortions and excursions, and many retrograde actions; see Ps 125:5;

and they froward in their paths; declining here and there, sometimes going one way and sometimes another, but always following that which is evil, and resolute to continue therein.
