Exodus 16:18-20

Young's Literal Translation

¹⁸ and they measure with an omer, and he who is [gathering] much hath nothing over, and he who is [gathering] little hath no lack, each according to his eating they have gathered.

¹⁹ And Moses saith unto them, `Let no man leave of it till morning;'

²⁰ and they have not hearkened unto Moses, and some of them do leave of it till morning, and it bringeth up worms and stinketh; and Moses is wroth with them.
