Do not oppress ones fellow-man with words
“You shall not wrong a member of your nation” Vayikra Behar 25:17
We should not say to a Bal Tushuva “remember your past deeds”or to the son of a convert to Judaism “remember the deeds of your forefathers” or to ask a matter of wisdom from someone who has no wisdom, in order to distress him.
And any similar way of wronging with words.
Verbally wronging is greater than monetary wronging, money can be replaced but pain caused by verbally wronging cannot be undone, Talmud Baba Metzia 58b
