Matthew Poole and continuators on Exodus 2:21

21 And Moses was content to dwell with the man, and he gave Moses Zipporah his daughter .

Or, consented to his desire or offer. And so his present and temporary repose there is turned into a settled habitation.

Whom Moses married 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 40 years after this, Exod. 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.
