Exodus 16:1-3

1 And they took their journey from Elim, and all the congregation of the children of Israel came unto the wilderness of Sin, which is between Elim and Sinai, on the fifteenth* day of the second month after their departing out of the land of Egypt.
2 And the whole congregation of the children of Israel murmured against Moses and Aaron in the wilderness:
3 And the children of Israel said unto them, Would to God* we had died by the hand of the LORD in the land of Egypt, when we sat by the flesh pots, and when we did eat bread to the full; for ye have brought us forth into this wilderness, to kill this whole assembly with hunger.
