Proverbs 4:19-21

Amplified Bible

¹⁹ 
The way of the wicked is like [deep] darkness;
They do not know over what they stumble.^(A)

²⁰ 
My son, pay attention to my words and be willing to learn;
Open your ears to my sayings.
²¹ 
Do not let them escape from your sight;
Keep them in the center of your heart.
