Charles Ellicott 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.—Literally, as in the margin, fair to God. This adjective is found in the LXX. of Exodus 2:2, as applied to Moses. The special idiom for expressing pre-eminent excellence is itself essentially Hebrew, the highest goodness being thought of as that which proves itself good to God; but this also had become familiar to Hellenistic Jews through the LXX. version, as, e.g., in Jonah 3:3, a city “great to God” means an exceedingly great city. Saint Paul’s phrase mighty to God (2 Corinthians 10:4) is probably an example of the same idiom. Josephus, likely following some old tradition (Ant i. 9, § 6), describes the infant Moses’s beauty as so great that those who met him turned to gaze in admiration.
