2 A bastard shall not enter into the assembly of Yahweh; even to the tenth generation shall none of his enter into the assembly of Yahweh.

A bastard shall not enter. All agree that by the word mmzr, mamzer, a bastard is signified, who is born of an uncertain father; but they take it in different ways, For some extend it to all bastards who spring from fornication, whilst others imagine that it refers to those only whose origin is doubtful, and who are called vulgo geniti; viz, whose mothers, in their base and common prostitution of themselves, have brought it about by their gross licentiousness, that their children should be born from this monstrous medley, as it were. This second opinion I approve of most. But, by this symbol God would admonish the seed of Abraham how exalted was its dignity, as being separate from the polluted heathen. Meanwhile, He would not altogether exclude these unhappy persons from the hope of salvation, although, by no fault of their own, they were unable to give the name of their father; but He only humbled them by a temporal punishment, and desired that their example should be profitable to others.
A bastard - Probably, a child born of incest or adultery.
Even to his tenth generation - i. e. (see the next verse and Nehemiah 13:1), forever. Ten is the number of perfection and completeness.
A bastard shall not enter - ממזר mamzer, which is here rendered bastard, should be understood as implying the offspring of an illegitimate or incestuous mixture.
(b) A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD.
(b) This was to cause them to live chastely, that their posterity might not be rejected.
A bastard shall not enter into the congregation of the Lord,.... That is born of whoredom, as the Targum of Jonathan; and for the sake of avoiding whoredom and deterring from it was this law made, according to Maimonides (h), that adulterers might see, as he observes, that they affect their whole family with an irreparable stain, should they commit such an infamous action; though the Jews commonly interpret it of one that is born of any of those incestuous copulations forbidden in Leviticus 18:1 which they gather from this following upon, and being near unto one of those incests mentioned in the last verse of the preceding chapter (i); and it is a rule with them (k), that persons born of such copulations were reckoned bastards; now such an one, according to Jarchi, might not marry an Israelitish woman, or rather might not be admitted into the assembly of elders, or bear any public office. Jephthah may seem to be an objection to this, who was the son of an harlot, Judges 11:1 which might be owing to the badness of the times, the laws of God being neglected, or to the providence of God so ordering it, who is not bound by his own laws, though men are; nor was he the son of a common harlot, nor of an incestuous person, but of his father's concubine; besides some think such only are intended who were born of strangers and not Israelites:
even unto his tenth generation shall he not enter into the congregation of the Lord; which seems as if he might at the eleventh; but it is generally interpreted never, as is gathered from the following verse, and from the tenth number being an absolute and perfect one; yet according to the Jewish writers there were ways and means by which their posterity became legitimate; so they say, bastards may be purified (or legitimated), how? if one marries a servant maid, the child is a servant, who if he becomes free, (his) son is a free man (l).
(h) Targum Jonah. in loc. Misn. Yebamot, c. 8. sect. 2, 4, 5, 6. Maimon. Moreh Nevochim, par. 3. c. 49. (i) Bartenora in Misn. Kiddushin, c. 3. sect. 12. (k) Misn. Kiddushin, c. 3. sect. 12. & Misn. Yebamot, c. 4. sect. 13. Jarchi & Aben Ezra in loc. (l) Misn. Kiddushin, c. 3. sect. 13.
So also with the ממזר, i.e., not persons begotten out of wedlock, illegitimate children generally (lxx, Vulg.), but, according to the Talmud and the Rabbins, those who were begotten in incest or adultery (cf. Ges. thes. p. 781). The etymology of the word is obscure. The only other place in which it occurs is Zac 9:6; and it is neither contracted from מוּם and זר (according to the Talmud, and Hitzig on Zac 9:6), nor from זר מעם (Geiger Urschr. p. 52), but in all probability is to be derived from a root מזר, synonymous with the Arabic word "to be corrupt, or foul." The additional clause, "not even in the tenth generation," precludes all possibility of their ever being received. Ten is the number of complete exclusion. In Deuteronomy 23:3, therefore, "for ever" is added. The reason is the same as in the case of mutilated persons, namely, their springing from a connection opposed to the divine order of the creation.
The congregation - Taking the word as in the former verse.
