Proverbs 7:2-4

Amplified Bible

² 
Keep my commandments and live,
And keep my teaching and law as the apple of your eye.
³ 
Bind them [securely] on your fingers;
Write them on the tablet of your heart.
⁴ 
Say to [skillful and godly] wisdom, “You are my sister,”
And regard understanding and intelligent insight as your intimate friends;
