Clement of Alexandria, on Jude 1:5

“I will therefore admonish you, though ye once knew all things, that Jesus, having saved the people out of the land of Egypt, did afterwards destroy them that believed not:”

“"For the Lord God," he says, "who once delivered a people out of Egypt, afterward destroyed them that believed not;" that is, that He might train them through punishment. For they were indeed punished, and they perished on account of those that are saved, until they turn to the Lord.”
