Theophylact of Ohrid

"And Moses was learned in all the wisdom of the Egyptians." Neither Moses, nor Ananias and Daniel with those who were with them, would have received a foreign education if necessity and the violence of despots had not compelled them to it, because it was of no use to them for anything—unless, perhaps, someone might say that receiving an education was good in order to uproot the errors of the Egyptians.

Oecumenius

When he was exposed and Pharaoh's daughter took him up, she taught him all the wisdom of the Egyptians. From this it is clear that external instruction outside the Scriptures is not entirely rejectable. For in the manner of praise it is said that Moses was educated in all the wisdom of the Egyptians. And concerning the three youths and Daniel, that they excelled all in Chaldean philosophy and in the other sciences. (Dan. 1:17) Yet one must attend to these things briefly, remaining faithful to the God-breathed Scripture.
