Exodus 16:29

26 six days ye do gather it, and in the seventh day -- the sabbath -- in it there is none.`

27 And it cometh to pass on the seventh day, some of the people have gone out to gather, and have not found.

28 And Jehovah saith unto Moses, `How long have ye refused to keep My commands, and My laws?

29 see, because Jehovah hath given to you the sabbath, therefore He is giving to you on the sixth day bread of two days; abide ye each [in] his place, no one doth go out from his place on the seventh day.`

30 And the people rest on the seventh day,

31 and the house of Israel call its name Manna, and it [is] as coriander seed, white; and its taste [is] as a cake with honey.

32 And Moses saith, `This [is] the thing which Jehovah hath commanded: Fill the omer with it, for a charge for your generations, so that they see the bread which I have caused you to eat in the wilderness, in My bringing you out from the land of Egypt.`
