YAHUAH gave his people Yashar'el and Yahudah the sixth day as a preparation day to prepare for Shabbat so that we do not cook or prepare any food or do any work on the Shabbat day.

22And it came to be, on the sixth day, that they gathered twice as much bread, two omers for each one. And all the rulers of the congregation came and told Mosheh.

23And he said to them, “This is what יהוה has said, ‘Tomorrow is a rest, a Sabbath set-apart to יהוה. That which you bake, bake; and that which you cook, cook. And lay up for yourselves all that is left over, to keep it until morning.’ ”

24And they laid it up till morning, as Mosheh commanded. And it did not stink, and no worm was in it.

25And Mosheh said, “Eat it today, for today is a Sabbath to יהוה, today you do not find it in the field.

26“Gather it six days, but on the seventh day, which is the Sabbath, there is none.”

27And it came to be that some of the people went out on the seventh day to gather, but they found none.

28And יהוה said to Mosheh, “How long shall you refuse to guard My commands and My Torota?

29“See, because יהוה has given you the Sabbath, therefore He is giving you bread for two days on the sixth day. Let each one stay in his place, do not let anyone go out of his place on the seventh day
