Proverbs 7:3-5

Amplified Bible

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;
⁵ 
That they may keep you from the immoral woman,
From the foreigner [who does not observe God’s laws and] who flatters with her [smooth] words.
