Our parsha is the source for the Torah's aversion to abusive speech. Halakha labels this prohibition “Onaat Devarim” – verbal oppression – and it is is articulated by Maimonides in the following manner:
“For instance, if a person is newly religious one must not say to him: "Remember your former deeds."
If a convert comes to study Torah, one must not say to him: "Shall the mouth that ate unclean and forbidden food study Torah which has been given by the Lord?"
If a person has been afflicted with disease and suffering, or if he has buried his children, one must not say to him in the words used by Job's companions in addressing Job: "… what guiltless man has ever perished?" (Job 4:6-7).” (Mishneh Torah, Laws of Transactions 14:13)
What do each of these cases have in common?
Why should a person not remind a penitent or a convert of his former life?
Why should a person refrain from suggesting that an individual is suffering because of their sins?
What are the friends of this sufferer thinking? Do they intend to heal or to harm? If they intend to heal, then what’s the problem?
When we look at the examples articulated by the Rambam, we appreciate their common thread. They are united in the humiliation or shame that they might engender. People who have moved on in life, developed new identities, do not necessarily want to be reminded of their background (whether non-Jewish or non-observant). If someone is sick, they don’t need to be driven lower with the prospect that they have caused their own misfortune. Emotional hurt is real, and the Torah drives this home by drawing an equation between psychological injury, emotional pain, and financial damage.
How so? This law emerge from a redundancy in the language of our parsha. We read:
When you sell an item to your neighbor, or purchase from your neighbor, you shall not mistreat (exploit - tonu) one another. (25:14)
This is a law of “Ona’ah” which forbids financial exploitation, overcharging, and unfair profit margins. It is wrong to take advantage of an unsuspecting customer. But only a few verses later we read what seems like a repetition:
Do not mistreat (tonu) one another, but fear your God; for I the Lord am your God. (25:17)
Is the Torah repeating itself? The first verse speaks of abuse, or maltreatment in the financial sphere. But the second verse speaks of abuse or exploitation without a specific application. The Talmud suggests that plain "mistreatment" must be through speech rather than any more concrete form of action:
“When it says: “When you sell … or purchase from your neighbor, you shall not mistreat (exploit - tonu) one another.” (25:14) monetary abuse is explicitly stated. How then do I realize the meaning of the verse: “And you shall not mistreat one another”? It is with regard to verbal abuse (Ona’at Devarim).” (Bava Metzia 58b)
Just as there is a law against defrauding in commerce, so there is a law against wronging a person by means of speech, as it is written: "You shall not mistreat one another, but you shall fear God.” This refers to wounding the feelings of another by words.
… Verbal maltreatment is more severe that financial exploitation because restitution can be made for one and not the other; one is financial, while the other is personal.” (ibid. 12,18)
Here is another example:
“It is forbidden to call a person by their nickname, even if it is a name that he is known by, if your purpose it to embarrass that person.” (Shulchan Aruch, Hoshen Mishpat 228:5)
Any speech that makes a person squirm is problematic.
So let’s discuss this:
When have you felt hurt by speech? How did it feel?
