וַיֹּ֧אמֶר יְהוָ֛ה אֶל־הַשָּׂטָ֖ן מֵאַ֣יִן תָּבֹ֑א וַיַּ֨עַן הַשָּׂטָ֤ן אֶת־יְהוָה֙ וַיֹּאמַ֔ר מִשּׁ֣וּט בָּאָ֔רֶץ וּמֵֽהִתְהַלֵּ֖ךְ בָּֽהּ׃
האָט גאָט געזאָגט צום שׂטן: פֿון װאַנען קומסטו? האָט דער שׂטן געענטפֿערט גאָט, און האָט געזאָגט: פֿון װאַנדערן איבער דער ערד און פֿון אַרומגײן אױף איר.

שטו העם ולקטו, “the people would leave the camp and collect;” the word שטו is familiar to us from Job 1,7 שוט, “roaming.” According to a midrash found in the Talmud, tractate Yuma folio 75, the line: שטו העם ולקטו, refers to the righteous Israelites who were eating the manna while it was descending through the atmosphere. They did not even have to bother to leave their homes and to collect it.
Rabbeinu Bahya
שטו העם ולקטו וטחנו ברחים או דכו, “the people would stroll and gather it, and grind it in a mill or pound it in a mortar.” We know the expression שטו from Job 1,7 when Satan described himself as roaming all over earth. This indicates that when the people went out to collect the manna they did not do so in groups, but each one pursued a different path. The word ולקטו “and they collected,” means that the manna was ready to be eaten forthwith. It did not have to be cooked, baked, or fried.
Rashbam
שטו, the expression occurs also in Job 1,7 and in Jeremiah 5,1 and in both instances refers to “roaming over an area.”
