וביום השביעי שבת, “and the seventh day is to be a day of rest called Sabbath; the people who were lacking in faith however, were saying that Friday and the following night were called Sabbath; the proof that this is what they thought is that when Moses upbraided them he says to them: “it is Sabbath today;” the emphasis on the word: “today” is meant as opposed to yesterday and last night. He had also told them on Friday: “tomorrow is the holy day Sabbath you will not find any.” (verse 23) The people who believed that the night follows the day in the Jewish calendar had been wrong all along, as Moses had made plain from the way he described the law concerning the eating of matzo on the Passover festival, that it would be from the evening of the 14/15th of Nissan until the 21st day of the month. In addition he had said to them in Leviticus 23,32 that the Day of Atonement commences on the evening and lasts until the following evening.

יצאו מן העם ללקוט, “some of the people left the camp intending to gather in manna;” they desecrated the Sabbath by doing so because they took their containers with them. They had already been told that this day was the day of the Sabbath when Moses had told them: “tomorrow is a holy day to G-d.” (verse 23)
