הָאֲנָשִׁ֨ים הָאֵ֜לֶּה שְֽׁלֵמִ֧ים הֵ֣ם אִתָּ֗נוּ וְיֵשְׁב֤וּ בָאָ֙רֶץ֙ וְיִסְחֲר֣וּ אֹתָ֔הּ וְהָאָ֛רֶץ הִנֵּ֥ה רַֽחֲבַת־יָדַ֖יִם לִפְנֵיהֶ֑ם אֶת־בְּנֹתָם֙ נִקַּֽח־לָ֣נוּ לְנָשִׁ֔ים וְאֶת־בְּנֹתֵ֖ינוּ נִתֵּ֥ן לָהֶֽם׃
די דאָזיקע מענטשן זײַנען אין שלום מיט אונדז; זאָלן זײ זיך באַזעצן אין לאַנד, און פֿאַרקערן דרינען; װאָרום זעט, דאָס לאַנד ליגט געראַם אין אָרט פֿאַר זײ. זײערע טעכטער װעלן מיר אונדז נעמען פֿאַר װײַבער, און אונדזערע טעכטער װעלן מיר זײ געבן.

רחבת ידים, “enough large places:” we find the word: יד used in this sense also in Deuteronomy. 23,13 ויד תהיה לך, “you shall have a small place there” and explained in this sense by Ibn Ezra.
Ramban
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.”

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”.
