A.T. Robertson Commentary Acts 7:20

"At which season Moses was born, and was exceeding fair; and he was nourished three months in his father`s house." — Acts 7:20 (ASV)

Exceeding fair (αστειος τω θεω). Ethical dative, fair to God (as God looked at him). Αστειος is from αστυ, city, and so means "of the city," with city manners and polish. Old word, only twice in the N.T. and both times about Moses and taken from Ex 2:2.

He was nourished (ανετραφη). Second aorist passive indicative of ανατρεφω. He was brought up at home for three months in defiance of the new Pharaoh.
