Charles Spurgeon Commentary Exodus 16:1-2

"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. And the whole congregation of the children of Israel murmured against Moses and against Aaron in the wilderness:" — Exodus 16:1-2 (ASV)

They have been only about six weeks in the wilderness, and already they are up in arms against their leaders. Remember that we have the same kind of people to deal with as Moses and Aaron had.

The children of Israel were no better than any other nation; and I do not think they were any worse. We may take them as a fair average of human nature, which is a discontented, rebellious thing in the best of circumstances.
