גשו נא אלי. רָאָה אוֹתָם נְסוֹגִים לְאָחוֹר, אָמַר עַכְשָׁו אַחַי נִכְלָמִים, קָרָא לָהֶם בְּלָשׁוֹן רַכָּה וְתַחֲנוּנִים, וְהֶרְאָה לָהֶם שֶׁהוּא מָהוּל (בראשית רבה):

גשו נא אלי STEP NEAR TO ME, I PRAY YOU — He saw that they recoiled and he said to himself “Now my brothers feel ashamed”. He therefore called to them and showed them that he was circumcised. (Genesis Rabbah 93:10).
