Exodus 16:16 WEB

¹⁴  When the dew that lay had gone, behold, on the surface of the wilderness was a small round thing, small as the hoar-frost on the ground.

¹⁵  When the children of Israel saw it, they said one to another, 'What is it?' For they didn't know what it was. Moses said to them, 'It is the bread which Yahweh has given you to eat.'

¹⁶  This is the thing which Yahweh has commanded: 'Gather of it everyone according to his eating; an omer a head, according to the number of your persons, shall you take it, every man for those who are in his tent.'

¹⁷  The children of Israel did so, and gathered some more, some less.

¹⁸  When they measured it with an omer, he who gathered much had nothing over, and he who gathered little had no lack. They gathered every man according to his eating.
