Exodus 16:18-20 Young's Literal Translation (YLT)
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.
Exodus 16:18-20 New International Version (NIV)
18 And when they measured it by the omer, the one who gathered much did not have too much, and the one who gathered little did not have too little. Everyone had gathered just as much as they needed.
19 Then Moses said to them, “No one is to keep any of it until morning.”
20 However, some of them paid no attention to Moses; they kept part of it until morning, but it was full of maggots and began to smell. So Moses was angry with them.
