Exodus 16:9-12

9And Moses spake unto Aaron, Say unto all the congregation of the children of Israel, Come near before Yhwh: for he hath heard your murmurings. 10And it came to pass, as Aaron spake unto the whole congregation of the children of Israel, that they looked toward the wilderness, and, behold, the glory of Yhwh appeared in the cloud.

11And Yhwh spake unto Moses, saying, 12I 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 Yhwh your God.
