37:22ל״ז:כ״ב
1 א

למען הציל אתו. רוּחַ הַקֹּדֶשׁ מְעִידָה עַל רְאוּבֵן שֶׁלֹּא אָמַר זֹאת אֶלָּא לְהַצִּיל אוֹתוֹ שֶׁיָּבֹא הוּא וְיַעֲלֶנּוּ מִשָּׁם, אָמַר אֲנִי בְכוֹר וְגָדוֹל שֶׁבְּכֻלָּן, לֹא יִתָּלֶה הַסֵּרָחוֹן אֶלָּא בִי:

למען הציל אתו THAT HE MIGHT DELIVER HIM [OUT OF THEIR HAND] — The Holy Spirit (Scripture) bears witness for Reuben that he said this only for the purpose of saving his brother — that he would come afterwards and draw him up from there. He thought, “I am the first-born and the chief among them, and blame will attach to no one but myself” (Genesis Rabbah 84:15).
