Instruction about the mouth
7 Listen, my children, to instruction about your mouth; whoever follows my instruction will never succumb to it.
8
The lips of sinners will seize them and make abusers and the arrogant stumble.
9
Don't let your mouth get used to making solemn pledges, and don't get accustomed to saying the name of the holy one.
10
Just as a household slave who is constantly examined won't be lacking bruises, so also the person who always swears and speaks the Lord's name will never be cleansed from sin.
11
People who make many solemn pledges will be full of lawlessness, and a scourge won't depart from their house. If they break their solemn pledges, their sin is on them, and if they disregard it, they sin doubly, and if they swear falsely, they won't be justified, but their houses will be full of misery.
12
There is a way of speaking that's comparable to death; don't let it be found among Jacob's descendants. All these things will stay far away from the godly, and they will not wallow in their sins.
13
Don't grow accustomed to saying coarse things, because to do so is to engage in sinful speech.
14
Remember your father and mother, because you sit in the council among officials. This way, you won't forget yourself in front of them and act foolishly out of habit— then you'd wish that you hadn't been born, and you'd curse the day of your birth
15
People who are accustomed to reproachful words will never learn anything their whole life.
