For the children of Israel walked forty years in the wilderness, until all the nation, even the men of war who came forth out of Egypt, were consumed, because they didn't listen to the voice of Yahweh: to whom Yahweh swore that he wouldn't let them see the land which Yahweh swore to their fathers that he would give us, a land flowing with milk and honey.
"The reproach of Egypt here is enigmatical.  It would seem that the reproach was the non-covenant status of Israel as a mixed multitude, not yet adequately formed into a religious community."[15]  There would also appear to be a possible reference here to the paganism the Jews had encountered in Egypt, and in some degree adopted (See Stephen's speech in  Acts 7).  There is a stigma that exists for all people of any age who are NOT in covenant relations with God.  Boling stated that the "reproach" had something to do with "freedom from the scorn and indignity of slavery."[16]
