Deuteronomy 21:18

21:18 If a person has a stubborn, rebellious son who pays no attention to his father or mother, and they discipline him to no avail, ¹ 

Deuteronomy 27:22

27:22 ‘Cursed is the one who has sexual relations with his sister, the daughter of either his father or mother.’ Then all the people will say, ‘Amen!’

Deuteronomy 14:21

14:21 You may not eat any corpse, though you may give it to the resident foreigner who is living in your villages ²  and he may eat it, or you may sell it to a foreigner. You are a people holy to the Lord your God. Do not boil a young goat in its mother’s milk. ³ 

[21:18]  ¹ tn Heb “and he does not listen to them.”

[14:21]  ² tn Heb “gates” (also in vv. 27, 28, 29).

[14:21]  ³ sn Do not boil a young goat in its mother’s milk. This strange prohibition – one whose rationale is unclear but probably related to pagan ritual – may seem out of place here but actually is not for the following reasons: (1) the passage as a whole opens with a prohibition against heathen mourning rites (i.e., death, vv. 1-2) and closes with what appear to be birth and infancy rites. (2) In the other two places where the stipulation occurs (Exod 23:19 and Exod 34:26) it similarly concludes major sections. (3) Whatever the practice signified it clearly was abhorrent to the Lord and fittingly concludes the topic of various breaches of purity and holiness as represented by the ingestion of unclean animals (vv. 3-21).
