Even before the Exodus, Danaus and Cadmus sailed with their followers to Greece. Most of the Israelites later moved with Moses through the desert to Judea/Canaan:

"All the foreigners were forthwith expelled, and the most valiant and noble among them, under some notable leaders, were brought to Greece and other places, as some relate, the most famous of their leaders Danaus and Cadmus. But the majority of the people descended into a country not far from Egypt, which is now called Judaea....The leader of this colony was one Moses, a very wise and valiant man".
Diodorus Siculus - Library of History - 40.3

Danaus settled in Argos and became the progenitor of the Danaans;
"They say also that those who set forth with Danaus, likewise from Egypt, settled what is practically the oldest city in Greece, Argos".
Diodorus Siculus - Library of History 1.28

@wotsup I remember when i was a young child, maybe 5-7 my grandfather would take me up the mountains in Argos and tell me stories of his great grandfather. Later in my teens and 20's I use to think those stories were fairy tales. Not anymore.
