Exodus 16:20-24

But they did not listen to Moses, and some left part of it until morning, and it bred worms and stank; and Moses was angry with them.

They gathered it morning by morning, everyone as much as he would eat; but when the sun became hot, it would melt. The Sabbath

Now on the sixth day they gathered twice as much bread, two omers for each one. When all the leaders of the congregation came and told Moses,

then he said to them, “This is what the Lord meant: Tomorrow is a Sabbath observance, a holy Sabbath to the Lord. Bake what you will bake and boil what you will boil, and all that is left over put aside to be kept until morning.”

So they put it aside until morning, as Moses had ordered, and it did not stink nor was there a maggot in it.
