Exodus 16:21-23

Young's Literal Translation

²¹ And they gather it morning by morning, each according to his eating; when the sun hath been warm, then it hath melted.

²² And it cometh to pass on the sixth day, they have gathered a second bread, two omers for one, and all the princes of the company come in, and declare to Moses.

²³ And he saith unto them, `It [is] that which Jehovah hath spoken [of]; a rest -- a holy sabbath to Jehovah -- [is] to-morrow; that which ye bake, bake; and that which ye boil, boil; and all that is over, let rest for yourselves in charge till the morning.'
