Proverbs

Thorns grew abundantly in the lands of the Bible (15:19). In both the OT and NT, thorns were used as instruments of torture and punishment. During the crucifixion, Roman soldiers mocked Jesus by placing a crown made from thorns on his head (Matt. 27:29).
Tents were the most common type of housing in biblical times, as is the case in some parts of the world today. The simple structure and sparse furnishings made them easy to move from place to place. Tents were made by setting poles in the ground, then stretching animal skin or cloth over the poles. Curtains could be used inside the tent to divide it into rooms. Mats often covered the floor, with an open area left in the middle for building a fire.
What does it mean to be prudent? The “prudent” person (13:16) is one who uses good sense. A prudent person carefully thinks through situations and their possible consequences and acts accordingly. Prudence also involves carefully managing resources so that one has what is needed in the future.
What is an “abomination”? When the Bible refers to something as an “abomination” (12:22), it means that it is repulsive or detestable to the Lord. Things that are an abomination are contrary to the will of God and his commandments.
A different kind of security. In biblical times, if a person was unable to pay his debt, the consequences could be serious. The whole family could be sold into slavery. If someone put up “security” for another person, he promised to pay that person’s debt if he was unable to do so himself. Proverbs teaches that putting up security for another person is generally unwise, since those who do so risk losing everything if the other person cannot pay his debt (11:15).
Vinegar (10:26) is wine that has soured. Though generally made from grapes, vinegar can be made with many different fruits. It was often used for seasoning food and bread (Ruth 2:14).
The fact that the house of Wisdom has seven pillars (9:1) could signify perfection. Or, it could simply mean that Wisdom’s house is large and impressive.
