Matthew Henry on Proverbs 4:20–end
Solomon, having warned us not to do evil, here teaches us how to do well. It is not enough for us to shun the occasions of sin, but we must study the methods of duty.
I. We must have a continual regard to the word of God and endeavour that it may be always ready to us.
1. The sayings of wisdom must be our principles by which we must govern ourselves, our monitors to warn us of duty and danger; and therefore, (1.)

Incline thine ear to my sayings.
21 Let them not depart from thine eyes;
Keep them in the midst of thine heart.
22 For they are life to all who get possession of them,
And health to their whole body.

This supposed causative meaning it has also here: may they = may one (vid., under Pro 2:22) not remove them from thine…
