Ulangan 21:19

21:19 his father and mother must seize him and bring him to the elders at the gate of his city.

Ulangan 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!’

Ulangan 32:7

32:7 Remember the ancient days;

bear in mind ¹  the years of past generations. ² 

Ask your father and he will inform you,

your elders, and they will tell you.

[32:7]  ¹ tc The Syriac, Targum, and Vulgate read 2nd person masculine singular whereas the MT has 2nd person masculine plural. The former is preferred, the latter perhaps being a misreading (בִּינוּ [binu] for בִּינָה [binah]). Both the preceding (“remember”) and following (“ask”) imperatives are singular forms in the Hebrew text.

[32:7]  ² tn Heb “generation and generation.” The repetition of the singular noun here singles out each of the successive past generations. See IBHS 116 §7.2.3b.
