Exodus 2:21

Moses was content; or, consented to this desire or offer. And so his present and temporary repose there is turned into a settled habitation. Moses married Zipporah not instantly, but after some years of acquaintance with the family, as may probably be gathered from the youngness and uncircumcisedness of one of his sons forty years after this, Exodus 4:25. In which time, as Moses would not fail to instruct them in the knowledge of the true God, which he was able excellently to do, so it is likely he had succeeded therein in some measure, and therefore married Zipporah.
