Seforno: They were permitted to collect as much or as little as they wanted. However, nobody would arrive home with less or with more than he normally ate. In fact, upon measuring what he had collected, he would find that he had collected exactly one Omer ¹ for each person in his household. ²

R. Bachye (citing R. Chananel): "la'asher be'Ohalo" refers to his wife ¹ and "Mispar Nafshoseihem", to the small children in his tent ? to teach us that a man is obligated to sustain his wife and small children. ^{2 3}
