Imamat 18:16

18:16 You must not have sexual intercourse with your brother’s wife; she is your brother’s nakedness. ¹ 

Imamat 18:19

18:19 “‘You must not approach a woman in her menstrual impurity ²  to have sexual intercourse with her.

Imamat 22:31

22:31 “You must be sure to do my commandments. ³  I am the Lord.

[18:16]  ¹ sn Regarding the last clause, see the notes on vv. 7 and 10 above.

[18:19]  ² tn Heb “in the menstruation of her impurity”; NIV “during the uncleanness of her monthly period.”

[22:31]  ³ tn Heb “And you shall keep my commandments and you shall do them.” This appears to be a kind of verbal hendiadys, where the first verb is a modifier of the action of the second verb (see GKC 386 §120.d, although שָׁמַר [shamar, “to keep”] is not cited there; cf. Lev 20:8, etc.).
