Exodus 16:29-31

Young's Literal Translation

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.
