There are several factors that affect the spiritual life of a human being. When a man does not have knowledge of the word of God, he is like the wind, we do not know where he comes from or where he is going. In this way, he can easily fall into adultery, since the knowledge of the word of the Lord warns us about this.
Solomon makes a comparison between the thief and the adulterer. The thief, when he is discovered and faces justice, ends up paying more than he has stolen. However, he also mentions that the adulterer steals, but it is impossible for him to repay.
The mention, or rather this comparison, that Solomon makes in this verse between the thief and the adulterer makes it clear that the thief can restore what he has stolen and even more, but the adulterer cannot do so. This is due to lack of knowledge.
But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul.
Proverbs 6:32
Adultery is a sin that is committed out of desire, since it is the desire of man and the flesh. This unbridled desire causes the soul to become corrupted, as this proverb mentions.
Why does he who commits adultery lack understanding? Because he does not care for or control his flesh. It is a desire that is always present to deceive you and put you at odds with the Lord.
Solomon exhorts us to avoid falling into this unbridled desire of the flesh, because once in, restitution is difficult. Although there is no doubt that your life will change, this only happens if you return to the full knowledge of the Lord and remove this evil from your life.
