The account of their route may differ in detail, but the main incidents coincide.
Nennius, an English chronicler, who wrote in the seventh century, from the oral testimony of trustworthy Irish Celts, gives corroborative testimony.

He writes thus: "If any one would be anxious to learn how long Ireland was uninhabited and deserted, he shall hear it, as the most learned of the Scots have related it to me.[48] When the children of Israel came to the Red Sea, the Egyptians pursued them and were drowned, as the Scripture records.

In the time of Moses there was a Scythian noble who had been banished from his kingdom, and dwelt in Egypt with a large family.

He was there when the Egyptians were drowned, but he did not join in the persecution of the Lord's people.

Those who survived laid plans to banish him, lest he should assume the government, because their brethren were drowned in the Red Sea; so he was expelled.
