Translations
If someone has caused pain, he hasn't only hurt me — he has hurt all of you, to some degree. I say 'to some degree' so as not to pile on.
Now if anyone has caused grief, it is not to me he has caused grief — but in part (so as not to press too hard) — to all of you.
But if any have caused grief, he hath not grieved me, but in part: that I may not overcharge you all.
Now if anyone has caused grief, he has not grieved me but all of you—to some degree, not to overstate it.
