I recently took these notes while listening to a sermon from the late Colin Smith – one of my favorite professors from college.
How to Tell a Librarian from a Prostitute

Proverbs 7:1-8
1 My son, keep my words
and treasure up my commandments with you;
2 keep my commandments and live;
keep my teaching as the apple of your eye*
3 bind them on your fingers;
write them on the tablet of your heart.
4 Say to wisdom, “You are my sister,”
and call insight your intimate friend,
5 to keep you from the forbidden woman,
from the adulteress with her smooth words
6 For at the window of my house
I have looked out through my lattice,
7 and I have seen among the simple,
I have perceived among the youths,
a young man lacking sense,
8 passing along the street near her corner,
taking the road to her house
*“The apple of your eye” – Whatever someone is looking at is reflected in the center of his or her eye. The idea here is to focus relentlessly on the teacher’s teaching.
Proverbs 1-8 are the “My son” Proverbs. They are speaking as a mother or father to their child teaching him what he needs to know to succeed in the world.
One of the recurring themes in speaking to a son is to keep him from the wrong kind of woman. This was especially important in the Old Testament because the people of God was continued through physical birth.
How does one pick a good spouse? That kind of discernment is not inbred. Discernment is the kind of wisdom and that allows one to see the difference between two or more things that look very similar.
God gives that kind of wisdom through His Word – and that’s what Proverbs is about.
Many people who grow up in the church grow up thinking that telling the difference between good and evil is as easy as telling the difference between a librarian and a prostitute. And typically the distinction is made even easier because the pastor tells us what’s good and bad.
But experience and the Scriptures tell us that the difference isn’t always that simple to detect.
Proverbs 9:13-18
The woman Folly is loud;
she is seductive and knows nothing.
She sits at the door of her house**;
she takes a seat on the highest places of the town,
calling to those who pass by,
who are going straight on their way
“Whoever is simple, let him turn in here!”
And to him who lacks sense she says,
“Stolen water is sweet,
and bread eaten in secret is pleasant.”
But he does not know that the dead are there,
that her guests are in the depths of Sheol.
**It was customary for women to stay indoors. Women who said in the doorway were typically very promiscuous.
The seductress in this text goes to great lengths to make herself known and seduce the simple one – the one who is naive and lacks the discernment that comes with maturity.
The chapter has a chiastic structure to it, meaning that the latter part of the chapter intentionally parallels the beginning. So here is the parallel text:
Proverbs 9:1-6
Wisdom has built her house;
she has hewn her seven pillars.
She has slaughtered her beasts; she has mixed her wine;
she has also set her table.
She has sent out her young women to call
From the highest places in the town,
“Whoever is simple, let him turn in here!”
To him who lacks sense she says,
“Come, eat of my bread
and drink of the win I have mixed.
Leave your simple ways, and live,
and walk in the way of insight.”
Both foolishness and wisdom are targeting your soul. And they both can sound the same at times.
The reason many college freshman question/leave the faith upon entering secular universities is because they have never been taught discernment. They have only been told in a black and white manner, “This is right. That is wrong.”
The world quickly makes it obvious that life isn’t that simple.
And that’s what the writer of Proverbs knew. Evil often imitates good, or uses enough good, to appear as good. And a regenerated heart of discernment will be what allows us to tell the difference.
Principles of Discernment
1. You can tell by the pitch; by what’s being sold.
- stolen water/secret bread – v. 17 (that which appeals to the flesh but is sinful)
- “I know it’s wrong, but…”
2. Wisdom is as readily available as folly, but it must be searched for.
Chiastic structure points to the center verse of the chapter:
9:10 “The fear of the LORD is the beginning of wisdom,
and the knowledge of the Holy One is insight.”
Two levels of wisdom in Proverbs:
1) Seeing how the world operates
2) Seeing the God behind how the world operates
The flesh puts man at the center of the universe. Wisdom puts God at the center.
Two levels of wisdom in this text:
1) Teaching a boy how to choose a good woman.
- There has never been a woman born, who doesn’t automatically assume that when it comes to women, men are stupid.
- A man can easily be deceived by the wiles of a woman – and women know it.
- Proverbs 7:6-24
2) Teach a boy how to seek wisdom
- We live in a world where people show what they think other people want to see in order to get what they want.
- To learn discernment, it starts with the fear of the Lord.
