Второзаконие 22:30

(or Deu 23:1) This verse, in which the prohibition of incest is renewed by a repetition of the first provision in the earlier law (Lev 18:7-8), is no doubt much better adapted to form the close of the laws of chastity and marriage, than the introduction to the laws which follow concerning the right of citizenship in the congregation of the Lord.

The laws of this chapter provide, I. For the preservation of charity and good neighbourship, in the care of strayed or fallen cattle (Deu 22:1-4). II. For the preservation of order and distinction, that men and women should not wear one another's clothes (Deu 22:5), and that other needless mixtures should be avoided (Deu 22:9-11). III. For the preservation of birds (Deu 22:6, Deu 22:7). IV. Of life (Deu 22:8). V. Of the commandments (Deu 22:12). VI. Of the reputation of a wife abused, if she were innocent (Deu 22:13-19), but for her punishment if guilty (Deu 22:20, Deu 22:21). VII. For the preservation of the chastity of wives (Deu 22:22). Virgins betrothed (Deu 22:23-27), or not betrothed (Deu 22:28, Deu 22:29). And, lastly, against incest (Deu 22:30).

22:30 The phrase his father’s former wife does not refer to a man’s own mother because incest was a more serious crime (see Lev 18:7-8, 29).
