Deuteronomy 23:1-2

He that is wounded It is generally agreed that Moses is here speaking of eunuchs. Shall not enter into the congregation of the Lord The meaning is, not that they should be debarred from the public worship of the true God, as the phrase sometimes signifies, for that privilege was granted to all nations indiscriminately, provided they renounced idolatry, Exodus 12:48; Leviticus 22:18; Numbers 9:14. But the sense seems to be, that such a one should not be deemed an Israelite, nor have his name entered in the public register; and especially that he should not be admitted to honours or offices, either in the church or commonwealth of Israel, or be allowed to be one of the society of elders, or rulers of the people, or to sit in council with them. The same privilege was denied to those here termed bastards, under which name the Jews comprehended not only those begotten in simple fornication, but also the offspring of all such incestuous marriages, as are prohibited Leviticus 18. One chief reason of this law, no doubt, was, to deter people from such unlawful connections as would both offend God, and leave an indelible blot upon their posterity.
