(8) The children that are begotten of them From this passage it is clear that it was not only from Egypt that a "mixed multitude" came up with Israel. It seems to have been impossible to prevent some inter-marriages between Edom, Moab, and Israel when the Israelites passed through their land. Such a precept is suitable to the circumstances of Moses' time. It would be less necessary when the bulk of the people had gone over the Jordan and left Moab and Edom far behind.

23:1-8 We ought to value the privileges of God's people, both for ourselves and for our children, above all other advantages. No personal blemishes, no crimes of our forefathers, no difference of nation, shuts us out under the Christian dispensation. But an unsound heart will deprive us of blessings; and a bad example, or an unsuitable marriage, may shut our children from them.The children that are begotten of them, Of such as became proselytes:

shall enter into the congregation of the Lord in their third generation; not in the third generation from the time that this law was made, but from the time that any of them should embrace the true religion; their sons were the second generation, and their grandchildren the third; and such might be admitted into the congregation, and be reckoned as of them, both in their civil and church state, and be capable of serving even offices among them, and of marriage with them, as the Targum of Jonathan; which some of the Jews interpret of males only, for females, according to them, might be married immediately as soon as made proselytes, in which way they account for the lawfulness of Solomon's marriage of Pharaoh's daughter (p).
