Israelites gather manna in desert

Ex 16: 4

4 And the Lord said to Moses: Behold I will rain bread from heaven for you; let the people go forth, and gather what is sufficient for every day: that I may prove them whether they will walk in my law, or not.

Numb 11; 7-8

7 Now the manna was like coriander seed, of the colour of bdellium. 8 And the people went about, and gathering it, ground it in a mill, or beat it in a mortar, and boiled it in a pot, and made cakes thereof of the taste of bread tempered with oil.
