Exodus 16:18-20 21st Century King James Version (KJ21)
18 And when they measured it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating.
19 And Moses said, “Let no man leave any of it until the morning.”
20 Notwithstanding, they hearkened not unto Moses; but some of them left part of it until the morning, and it bred worms and stank. And Moses was 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.
