[Avodah] Vehoyo einecho ro'oys es Morecho

[SBA]

It is quite common to see the quote "Vehoyo einecho ro'os es Morecho"
captioned above or below a picture of a rav/rebbe/RY etc.

To be honest, I never gave it much thought and wasn't even sure if it was a
posuk, a Chazal or whatever.

But learning Rashi this week on "Ko'eis ye'omar leYaakov" [23:23], he quotes
it (from Yeshaya 30:20) and it clearly refers to HKBH.

So now I ask, is it right to use this for a bosor vedam?
