Exodus 16:18-20 Darby Translation (DARBY)
18 And they measured with the omer: then he that gathered much had nothing over, and he that gathered little wanted nothing: they had gathered every man according to the measure of his eating.
19 And Moses said to them, Let no man leave [any] of it until the morning.
20 But they did not hearken to Moses; and some men left of it until the morning; then worms bred in it and it stank. And Moses was wroth with them.
