פּירוש אויף בראשית 34:21

שלמים means peaceable and whole hearted.

THESE MEN ARE PEACEABLE WITH US. The men of the city thought that they hated them as they saw them dejected, and it angered them very much. Perhaps they guarded themselves against them and installed in their city bars and doors, for Jacob’s sons were mighty men and valiant men for the war.¹⁷⁴Jeremiah 48:14. But now Hamor and his son Shechem told them, “Do not fear and do not keep distant from them for they are whole-hearted with us.”

האנשים האלה שלמים הם אתנו, they are quite peaceful towards us even though I raped their sister; the reason is that they are anxious to live side by side with us and to become one people. They are asking for a very minor concession on our part, that all out males must circumcise themselves as they are all circumcised themselves. He argued that acceptance of such a demand would not deprive his townsfolk of anything of value. In return for complying with their demand his countrymen would become co-owners of the extensive property of Yaakov’s family רחבת ידים לפניהם. Even though they do possess extensive herds and flocks, the land is more than adequate to support these animals without our having to limit the grazing land allocated to our livestock.

והארץ הנה רחבת ידים FOR THE LAND, BEHOLD, IT IS LARGE ENOUGH (literally, wide-handed) — the metaphor is that of a man whose hand is large and generous, and the idea is: “You will lose nothing if they dwell and trade in the land, for much merchandise is brought here and there are no buyers for it”.
