Exodus 16:8

16:8 And Moses said, [This shall be], when the LORD shall give you in the evening flesh to eat, and in the morning bread to the full; for that the LORD heareth your murmurings which ye murmur against him: and what [are] we? your murmurings [are] not against us, but against the LORD.

Exodus 16:12-13

16:12 I have heard the murmurings of the children of Israel: speak unto them, saying, At even ye shall eat flesh, and in the morning ye shall be filled with bread; and ye shall know that I [am] the LORD your God. 16:13 And it came to pass, that at even the quails came up, and covered the camp: and in the morning the dew lay round about the host.
