Комментарий к Берешит 45:4

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).

Yosef said "גשו נא אלי"-"come close to me". He showed them that he was circumcised. By doing this he wanted to show them his righteousness - that even though he was among people who were indulged with forbidden marriages, he didn't do the same. We find that it says in Tehillim "שישראל נגאלו ממצרים בזכות ד' דברים"- "that Bnei Yisrael got redeemed from Mitzrayim in the merit of 4 things" (1) they didn't change their clothes (2) they didn't change their names (3) they didn't speak Loshon Hara (4) they didn't intermarry. So too, here, Yosef let his brothers know in which merits they would be taken out of the future Galus and he is hinting to them that he is complete in all of those 4 matters. He didn't change his name, as he said: "I am Yosef". He didn't change his language, as he spoke to them in Loshon Hakodesh. He didn't intermarry, as he showed them that he was circumcised. He didn't speak Loshon Hara, as he said "come close to me "- because he didn't want Benyamin to hear about the selling and he didn't tell his father anything either. Yosef is also hinting to them that because of their sin of selling him, their children will be strangers. Like it says: "and now dont be sad", meaning, specifically NOW because in the future you will be sad. Therefore Yosef is also hinting to them about the Geula and the things that will bring the Geula. Some say that he is hinting to the ten killed leaders, that in the future they will be sad over the selling.

גשו נא אלי, so that not all the people hearing me cry can see that it is I who is crying.
