Adam Clarke on John 9:8

That he was blind - Ὁτι τυφλος ην: but, instead of this, προσαιτης, when he begged, or was a beggar, is the reading of ABC*DKL, seven others, both the Syriac, both the Arabic, later Persic, Coptic, Ethiopic, Armenian, Sahidic, Gothic, Slavonic, Vulgate, eight copies of the Itala, and some of the primitive fathers. This is in all probability the true reading, and is received by Griesbach into the text.

Beggars in all countries have a language peculiar to themselves. The language of the Jewish beggars was the following: זבי כי Deserve something by me - Give me something that God may reward you. רכי ני זכי גר מך O ye tender-hearted, do yourselves good by me. Another form, which seems to have been used by such as had formerly been in better circumstances, was this: סכי כי מה הוינא אסתכל בי מה אנא Look back and see what I have been; look upon me now, and see what I am. See Lightfoot.
